Good afternoon Mr. Chairman. I appreciate the opportunity to appear
before your Committee to discuss Railroad Safety.
The year 1996 has been a busy year for the National Transportation
Safety Board (NTSB) and a tragic year for the railroad and rail
transit industries. Since January 1, 1996, the Safety Board's
Railroad Division has launched on 14 railroad accidents resulted
in 19 fatalities, 226 injuries, and over $62 million in damages.
Included in these 14 accident investigations are 6 runaway trains,
4 collisions, 3 derailments, and 1 grade crossing accident.
RECENT SIGNIFICANT ACCIDENTS
Accidents on the Washington METRO in Gaithersburg, Maryland; the
Burlington Northern Santa Fe Railroad in Cajon Pass, California;
New Jersey Transit in Secaucus, New Jersey; and Maryland Transit
Administration's MARC Train in Silver Spring, Maryland are major
accident investigations involving full teams of NTSB investigators.
Other important accidents involving the Burlington Northern Santa
Fe Railroad in St. Paul, Minnesota and the Southern Pacific Railroad
in Tennessee Pass, Colorado are currently being investigated as
regional accidents by the Safety Board's regional accident investigators.
Each of these accidents involves important railroad safety issues.
Washington METRO, Shady Grove, Maryland
On Saturday, January 6, 1996 at about 10:40 pm a four car Washington
Metropolitan Transit Authority train, Train No. 111, operating
on the Red line, from Rockville to Shady Grove, collided head-on
with a six car "Gap" train which was standing on number
2 track beyond the end of the Shady Grove Station platform. The
operator of train 111 was killed in the collision. Two passengers
in the third car of train 111 were uninjured. The standing "Gap"
train, a train used to replace a train that has operational problems
and must be taken out of service, was unoccupied at the time of
the collision. At the time of the accident, the sky was cloudy
with moderate to heavy snow fall.
The operator of Train 111 was 48 years old and had only been a
train operator since October 27, 1995. Train 111 was being operated
in Automatic Mode (also known as Mode 1) on the surface section
of the Red Line in Montgomery County. According to transcripts
of the communications tapes, at about 10:25 pm, the operator of
Train 111 reported by radio to the Operations Control Center (OCC)
controller that upon entering the Twin Brook station, he had overrun
the station platform by four car lengths. The OCC controller instructed
the train operator to continue to the next station in Mode 1 Operation.
A short time later at 10:31 pm, the operator of train 111 reported
to the OCC control operator that he had overrun the Rockville
Station platform by one car length. The operator was told to disable
the doors on the first car and to service the Rockville Station.
The TWC computers show that train to wayside communications with
Train 111 were lost for one minute 58 seconds at the Rockville
station. It is believed that this interruption was due to the
Operator "Keying OFF" and then "Keying ON"
his train. "Keying OFF" is normally performed when the
operator switches control ends or needs to leave the control cab.
"Keying OFF" disables the propulsion system and applies
the brakes. "Keying on" brings all car systems on line
and ready for operation.
When the operator "Keyed OFF", Train 111 lost the Automatic
Train Supervision (ATS) information that was stored in its computer.
The ATS system was set to limit the train's speed to 59 mph, which
is the normal maximum speed for the run between Rockville and
Shady Grove. ATS information is updated at each station stop and
is used to pace train traffic and control the arrival time of
the train at the next station. Because the operator "Keyed
OFF" at the Rockville station, the ATS information was lost
and the Automatic Train Protection equipment limited the speed
of the train to a higher speed of 75 mph between the Rockville
and Shady Grove stations. Washington Metro considers 75 mph to
be a safe operating speed for this section of the Red Line - even
under adverse weather conditions.
About 10:34 pm, the operator of Train 111 reported to OCC that
he had a 75/75/75 - a 75 mph limiting speed; regulated at 75 mph;
with an actual speed of 75 mph.
About 10:37 pm, the OCC Controller asked Train 111 if his limiting
speed had dropped. The operator of Train 111 responded that the
limiting speed was down to 35 mph. This was the last communication
with the operator before the collision. The train overran the
Shady Grove Station by over 470 feet and collided with the standing
"Gap" train. The front of the unoccupied "Gap"
train was deformed ten inches. The striking train, however, telescoped
onto the standing train about 21 feet, killing the operator.
The Washington Metro system has had a policy of operating in Manual
Mode during inclement weather for the past 20 years. In memos
issued on November 17, 1995 and January 4, 1996, this policy was
rescinded. The memos essentially required that train operations
remain in Automatic Mode (Mode 1) during inclement weather.
The Safety Board is addressing the following issues in the Washington
METRO accident investigation:
Positive Train Separation (Control systems used to prevent train
collisions)
Performance of the Brake and Slip Slide Systems
Crashworthiness of Passenger Cars
Interface between the Transit Car and the ATC Equipment
Washington METRO's Safety Policies and Procedures
Operator and Controller Training and Experience
Burlington Northern Santa Fe Railroad, Cajon Pass, California
On February 1, 1996 a Burlington Northern Santa Fe (BNSF) freight
train, HBALT1-31, consisting of four locomotives and 49 cars (5,025
tons) was travelling westward, between Barstow and San Bernardino,
California on the Cajon Division when the train "ran away".
The train derailed at MP 60.7 after descending the Cajon Pass
at a speed of about 55 to 60 mph on a three percent downgrade.
The accident occurred about 4:10 am pst.
Two crewmen on board the BNSF train were killed in the accident.
The conductor and brakeman jumped or fell from the moving train
and sustained fatal injuries. The engineer stayed on the lead
locomotive and was seriously injured in the general derailment.
Two pipelines were located about 200 feet from the nearest wreckage.
The pipelines both carry jet fuel. The pipeline owners came to
the scene and clearly marked the pipeline location so that the
pipeline would not be damaged during wreck clearing operations.
Although the train was equipped with a two-way end of train device,
the device was not armed. The engineer and carman who performed
brake tests on the accident train before it began its descent
down the Cajon Pass stated to investigators that they attempted,
but were not successful in arming the two-way end of train device.
Arming the two-way end of train device enables the engineer to
put the train air brakes in emergency at the rear end of the train
by positioning a toggle switch in the lead locomotive. If the
device is not armed, the two-way end of train device acts as a
one-way end of train device where the engineer still receives
brake pipe air pressure readings, but cannot initiate an emergency
brake application at the rear of train.
Forty-five of the 49 cars derailed. The first and second locomotives
rolled over on their sides. All four locomotives and the derailed
equipment caught fire. Four of the cars that burned contained
hazardous materials. The derailed cars contained petroleum distillates,
butyl acetate, denatured alcohol, and trimethyl phosphate. Some
product spilled into the dry river bed of the Cajon River. An
evacuation of 1-1/2 mile radius was made involving about 60 people.
Interstate 15 was initially closed for over 48 hours immediately
after the accident. Interstate 15 was closed again two days later
due to fear that one of the hazardous material tank cars involved
in the accident might explode.
NTSB investigated a rear-end collision between a Union Pacific
freight train and a Santa Fe freight train on the Cajon Division
near this same location on December 14, 1994. The Board's report
of this accident (Report number NTSB/RAR-95/04) was adopted by
the Board on November 21, 1995, and will be discussed later in
this testimony.
The Safety Board investigators are pursuing the following issues
in the Cajon Pass, California accident:
Air Brake Inspection and Testing
Use of Two-Way End of Train Devices
Oversight of BNSF Operations
New Jersey Transit, Secaucus, New Jersey
About 8:40 am est, on February 9, 1996, New Jersey Transit Commuter
Train 1254, operating eastbound from Waldwick to Hoboken, New
Jersey, collided head-on with the lead locomotive of New Jersey
Transit Commuter Train 1107. Train 1107 was a westbound train
operating between Hoboken, New Jersey and Suffern, New York. Train
1107 consisted of a diesel locomotive and six passenger cars.
The train was configured with the diesel locomotive in front and
was manned by an operating crew of three. The collision took place
at Bergen Junction on the border line between Secaucus and Jersey
City, New Jersey.
The westbound train was operating on a clear signal and travelling
at about 53 mph in an area authorized for 60 mph. The eastbound
train left Harmon Cove station, accelerated to 53 mph, reduced
speed to 30 mph, then to 19 mph, and impacted the westbound train
at about seven mph. Train 1254 had passed a stop signal and fouled
the mainline when the collision took place.
There were over 400 passengers on the two trains. Three fatalities
and 162 injuries resulted from the collision. The engineers on
both trains were killed. One passenger who was riding in the cab
car at the leading end of the train 1254 was also killed. Of the
162 injuries, 75 were transported to local hospitals and seven
were admitted.
The operator of train 1254 was working a split shift. He reported
to work at 6:00 pm Thursday evening and operated trains until
about 1:00 am Friday morning. He was rested from 1:00 am until
5:40 am when he went back on duty operating trains. He was scheduled
to get off work at 7:30 am but he worked overtime and was assigned
to operate one more train. He "dead-headed" to Waldwick,
New Jersey and operated the accident train from Waldwick to the
collision site. The engineer's work schedule was in compliance
with the Federal Hours of Service regulations. The regulations
allow an engineer to work a 12 hour split shift provided that
the engineer is given a continuous rest period of at least 4 hours
duration between shifts.
On this part of the system, New Jersey Transit controls trains
through the engineer and the signal system. There are no automatic
stop features on this part of the system. New Jersey Transit relies
on the engineer adhering to the signal aspects to maintain safe
train operations.
The investigative team is looking into a variety of issues on
the Secaucus, New Jersey accident including:
Positive Train Separation
Signal Calling by Train Operators
Crashworthiness of Passenger Cars
Operator Fatigue and Rest Facilities
Operator Fitness for Duty
Maryland Transit Administration - MARC, Silver Spring, Maryland
On Friday, February 16, 1996, at about 5:38 pm, eastbound MARC
Train 286 consisting of three passenger cars and a locomotive,
collided nearly head on with westbound Amtrak Train 29, the Capital
Limited. The MARC train was operating in scheduled commuter service
between Brunswick, Maryland and Washington's Union Station. The
MARC train is a "push-pull" train with a locomotive
on one end and a cab car on the other which allows the train to
be operated from either end. The engineer was operating the train
from the cab car at the time of the collision. Amtrak Train 29,
the Capital Limited, consisted of two locomotives and 15 cars.
The train was travelling between Washington, D.C. and Chicago
Illinois. The Amtrak train departed from Washington's Union Station
about 20 minutes late due to a delay in servicing and coupling
the locomotives to the train.
At the time of the collision, the Amtrak train was travelling
west on track 2. The Train had been routed on track 2 to pass
a standing CSXT Freight train. According to signal records and
interviews with the crew of the standing freight train, the Amtrak
train was operating on an approach medium signal and just beginning
to negotiate a crossover from track 2 to track 1 at the time of
the collision.
At this time, signal tests are continuing, however, based on the
position of the crossover, the MARC train should have had an approach
signal about 2.6 miles before the accident scene and a stop signal
170 feet prior to the point of collision. If the signal system
was working properly, the MARC engineer should have received an
approach signal just before the Kensington Station. The approach
signal indicates that the engineer should not exceed 30 mph in
the signal block and be prepared to stop at the next signal. The
MARC Train passed this signal and immediately made a stop at the
Kensington Station. According to statements from a MARC train
operating in the opposite direction, the operator of Train 286
acknowledged the signal over the radio. The other MARC operator,
however, did not remember if the operator indicated that the signal
was clear or approach. The operator of train 286 made a short
station stop at Kensington. After he made the stop, he accelerated
his train to normal track speed. He did not limit his speed to
30 mph as would have been required if he had an approach signal.
According to the event recorder, the MARC train operator applied
emergency brakes about 1100 feet before the collision. At the
time he applied emergency brakes, the MARC train was travelling
about 63 mph. The train had slowed to about 40 mph at the time
of the collision. The Amtrak train was travelling at about 30
mph at the time of the collision. The stopping distance of the
MARC train from 63 mph is estimated to be about 2000 feet.
There were 164 passengers, 13 On Board Service personnel, four
operating crew, and one mechanical rider on the Amtrak train.
The Amtrak engineer and assistant engineer were injured in the
accident. There were three crewmembers and about 19 passengers
on board the MARC train. All three crew members and eight passengers
were killed in the accident and resulting fire.
The collision between the Amtrak locomotive and the MARC cab car
tore away the front left quadrant of the MARC cab car. At the
same time, the locomotive fuel tank on the lead Amtrak locomotive
ruptured and likely sprayed fuel in the vicinity of the MARC cab
car. All three MARC cars and the MARC locomotive were derailed
in the accident. Both Amtrak locomotives and the first eight cars
were derailed. The derailed Amtrak equipment consisted of six
Mail cars, one baggage car, and a transition dorm car. The transition
dorm car was the only occupied Amtrak car to derail.
The issues the Safety Board is pursuing in the Silver Spring,
Maryland accident are:
Positive Train Separation
Passenger Car Safety Standards
Emergency Exit Windows
Emergency Door Operations
Flammability of Car Components
Crashworthiness of Passenger Cars and Locomotive Fuel Tanks
Signal Placement
Signal Calling
Signal System Reliability
Attentiveness of Train Operators
Burlington Northern Santa Fe, St. Paul, Minnesota
On Wednesday, February 14, 1996, at 11:50 pm, Burlington Northern
Santa Fe Railroad freight train BN 01-144-14 (Extra 8572 East),
consisting of two locomotives and 89 cars, derailed 31 cars at
the Canadian Pacific Rail System (CPRS) Pig's Eye yard just east
of downtown St. Paul, Minnesota. The train was equipped with a
one-way end of train device. As a result of this accident, 11
persons were injured, two of them seriously. Preliminary estimates
of damage are in excess of $2 million.
The BNSF freight train had departed its initial terminal, Northtown
yard, which is about 12 miles from the accident site, and made
a brief stop about seven miles west of the CPRS yard. The engineer
used the train's air brakes to make this stop. The stop was made
at the top of a descending grade on the instructions of the train
dispatcher because of train movements routed into the CPRS yard.
When the dispatcher cleared the train to continue east, the engineer
started the train down the grade. When the train speed reached
30 mph, the engineer applied the dynamic brake. The engineer then
made a series of brake applications, but the speed of the train
increased.
The engineer placed the train air brakes in emergency and radioed
to the dispatcher and trains ahead that his train was out of control
at a speed of 49 mph. The train passed a signal displaying a "STOP"
indication about one mile from the entrance to the CPRS yard.
The BNSF freight train entered the CPRS yard and collided with
two standing, unoccupied CPRS locomotives and a standing, unoccupied
CPRS train which consisted of two locomotive units and 31 freight
cars. The BNSF train derailed on impact with the CPRS equipment
and then crashed into a yard office, destroying it. The building
was occupied by at least nine railroad employees, who were all
injured in the crash. Two of the railroad employees were injured
seriously.
Post accident inspection of the wheels on the first seven cars
of the Extra 8572 East exhibited indications of thermal distress,
commonly referred to as "blueing". A car inspector's
original record form indicated that the seventh head car had the
"A" end air brake pipe repaired prior to the train departing
the BNSF Northtown yard. The accident is still under investigation,
however, the Safety Board is examining a hose from the seventh
head car which may have been crimped closed.
The Safety Board is addressing the following issues in the St.
Paul, Minnesota accident:
Use of Two-Way End of Train Devices
Air Brake Inspection and Maintenance
Maintenance and Repair of Freight Cars
Southern Pacific Railway, Tennessee Pass, Colorado
On Wednesday, February 21, 1996, at about 5:47 am, mst, Southern
Pacific (SP) freight train 1-ASRVM-18 derailed two locomotives
and 39 cars at Tennessee Pass, Colorado. This accident resulted
in two fatalities and one serious injury. Preliminary damage estimates
exceed $10 million. The weather at the time of the accident was
snow with an ambient temperature of 32 degrees fahrenheit.
The SP freight train had made a running brake test, as required
by carrier operating rules, before cresting the summit at Tennessee
Pass. Event recorder information indicates that a brake application
was made and the train was brought to a stop before the train
began its descent down the 15 mile, 3% grade.
The event recorder readout also indicates that dynamic brake and
additional brake pipe reductions were utilized as the train proceeded
down the grade, but the speed of the train was not sufficiently
retarded and the train went into runaway condition.
The train derailed a total of 39 cars and both locomotives in
three locations; the general derailment occurred about eight miles
down the grade. The train had achieved a speed of 64 mph before
the general derailment occurred. The maximum authorized speed
in this area is 20 mph.
The train consisted of two locomotives and 82 freight cars, was
5614 tons, and 5800 feet in length. The operating crew consisted
of an engineer, a student engineer and a conductor. The engineer
and student engineer were in the operating compartment of the
lead locomotive and suffered fatal injuries; the conductor was
in the 2nd locomotive and was seriously injured. The conductor
stated to Safety Board investigators that the student engineer
was operating the locomotive when the train began its descent.
The train carried six cars of sulfuric acid; four of these cars
are known to have ruptured and released their entire contents.
The two additional cars were buried in the wreckage of the general
derailment. As a result of the hazardous material release, state
highway 24 was closed. Twenty-two motorists have reported injury
due to toxic fumes. A total of 12 residents were evacuated from
this rural area.
The Safety Board is addressing the following issues in the Tennessee
Pass, Colorado accident:
Use of Two-Way End of Train Devices
Air Brake Inspection and Maintenance
Engineer Training and Qualification
Release of Hazardous Substances
COMMON SAFETY ISSUES
The specific conditions under which these six accidents occurred
are all quite different. The safety issues, however, are very
similar. The safety issues that have been initially identified
in these accidents are not new safety issues, but safety issues
that the Safety Board has been addressing in their accident reports
and safety recommendations for years. Today, I would like to take
a minute to talk about five safety issues that appear in these
six accidents. The issues I will discuss are:
Positive Train Separation
Signal Calling
Two-Way End of Train Devices
Air Brake Inspection and Testing
Passenger Car Crashworthiness and Safety Standards
Positive Train Separation
The urgency of this issue has been highlighted over and over in
Safety Board Investigations since 1969. The more recent train
accidents that took place in Sugar Valley, Georgia; Corona, California;
Knox, Indiana; Ledger, Montana; Kelso, Washington; and Thedford,
Nebraska; could have all been prevented if a fully developed positive
train separation (PTS) system had been in place. And now, after
the tragic accidents that have occurred in the last two months,
we must add two other accidents to this list. Based on the factual
evidence gathered at the scene, the Safety Board investigators
feel that the accidents that occurred on New Jersey Transit in
Secaucus, New Jersey, and on the MARC Train in Silver Spring,
Maryland could have been prevented if a fully developed positive
train separation control system had been in place.
The Safety Board has long been an advocate of advanced control
systems that will provide positive train separation and act as
a safety net for human performance failures in the operation of
trains. Positive train separation is also on the NTSB's list of
Most Wanted Transportation Safety Improvements. About 70 to 80
percent of the railroad accidents investigated by the Safety Board
can be attributed to human error. The Safety Board believes that
new technology in the form of an advanced electronic system can
reduce the severity of human performance train operations accidents
by overriding the train operator's actions to prevent train collisions
and overspeed derailments.
Up until December of 1993, the NTSB was very discouraged with
the pace at which the railroad industry was developing an advanced
train control system that could provide positive train separation.
Since that time, however, there have been some important developments.
First, the Association of American Railroads and the railroads
they represent have entered into serious discussions on the AAR's
advanced train control system (ATCS) project. The discussions
addressed some important issues that need to be fully addressed
if ATCS or any other form of positive train separation system
is to be implemented. The participants in these discussions have
tried to define the system and identify its features. They have
also tried to determine the cost and the return on investment
for a fully implemented system.
Secondly, the Union Pacific and the Burlington Northern Santa
Fe railroads are working on a joint project to install an advanced
train control system that will provide positive train separation
on 750 miles of track in the Pacific Northwest. The system is
to use a combination of technologies to achieve positive train
separation including transponder and global positioning satellites
(GPS) to locate and monitor train movements. The test will be
the first real world field demonstration of advanced train control
technology since Burlington Northern's ARES project was cancelled
in 1992. The NTSB is very encouraged with these developments and
is anxious to see the actual system in operation.
In the Kelso, Washington report, the Safety Board reiterated Safety
Recommendations R-87-16 and R-93-12, made to the Federal Railroad
Administration on May 19, 1987 and July 29, 1993, respectively.
These recommendations form the foundation of the Safety Board's
effort to achieve Federal standards that will require the installation
and operation of a train control system on main line tracks that
will provide for positive separation of all trains. These recommendations
also call for the establishment of a firm timetable that includes
at a minimum, dates for implementation of a fully developed advanced
train control system, and commitment to a date for having the
advanced train control system ready for installation on the general
railroad system. These recommendations are classified Open--Acceptable
Response, based primarily on FRA's July 1994 report to Congress
entitled Railroad Communications and Train Control.
The Safety Board also made new positive train separation recommendations
to the FRA and the AAR in the Kelso, Washington report. Safety
Recommendations R-94-16 asked the Association of American Railroads
to identify and evaluate, in conjunction with the FRA, all of
the potential benefits of positive train separation and include
them in any cost benefit analysis conducted on positive train
separation control systems. AAR's initial response stated that
it was not possible to determine any business benefit from the
PTS test project being conducted in the Pacific Northwest. The
AAR went on to say that:
the Federal Railroad Administration (FRA) agrees that
railroads are "justified in insisting that the PTS debate
include a clear focus on safety costs and benefits". With
the proper focus on safety benefits, the Report to Congress correctly
evaluated the potential benefits of PTS and concluded that it
cannot be economically justified at this time.
The Federal Railroad Administration was also asked to evaluate
the business benefits of PTS in Safety Recommendation R-94-14.
This recommendation asked the Federal Railroad Administration,
in conjunction with the Association of American Railroads to identify
and evaluate all of the potential benefits of positive train separation
and include them in any cost benefit analysis conducted on positive
train separation control systems.
The Federal Railroad Administration responded to this recommendation
that evaluation of the nonsafety business benefits associated
with the UP/BN pilot project will not be feasible. The FRA went
on to support the AAR and the railroad's position that business
benefits should not be assessed. They also conclude that it is
not government's role to "substitute our judgement for the
judgment of senior railroad managers regarding matters within
their special expertise and responsibilities as corporate officers."
The Safety Board believes that the business benefits associated
with PTS are real and need to be included in the cost benefit
analysis. If safety is the only criteria for justifying PTS, then
the growth of PTS will be very slow. The Safety Board is concerned
that lack of understanding of the business benefits of PTS may
be used to label PTS control systems as - rightly or wrongly -
too costly for implementation.
While slow progress is being made, we would hope that the recent
rash of tragic accidents will spur the Federal Railroad Administration
and the industry to make a firm commitment to positive train separation
and establish a firm timetable for its implementation. The Safety
Board was pleased to see in the Federal Railroad Administration's
February 20, 1996 Emergency Order that "... the most effective
preventative measure is a highly effective train control system,"
especially automatic systems. We hope that these words can be
translated into action.
Signal Calling
Another safety issue that the Safety Board feels was involved
in at least two of these recent accidents involves signal calling.
Signal calling is an activity that can help keep train crews alert
and focused on safe operation of the train. Calling signals over
a radio also provides management with the opportunity to monitor
compliance with signal calling activity. The Safety Board feels
that requiring signals to be called over the radio may have helped
control distractions that may have been present in the New Jersey
Transit accident in Secaucus, New Jersey and the Maryland Transit
Administration MARC Train accident in Silver Spring, Maryland.
In recommendations made in 1976 and 1984, the Safety Board recommended
that engine crews communicate fixed signal aspects to other crew
members. The Federal Railroad Administration did not act on these
recommendations, instead opting to evaluate and improve the use
of radios for communication in the railroad industry. Nothing
concrete resulted from that project and the recommendation was
subsequently closed as unacceptable action.
In its February 20, 1996 Emergency Order, the Federal Railroad
Administration requires engineers on trains exceeding 30 mph and
not equipped with cab signals or automatic train control, to call
out to other crew members on the train, for acknowledgement, the
displayed aspect of restrictive signals that are passed.
Two-Way End of Train Devices
The Safety Board has been interested in two-way end of train devices
since the Helena, Montana accident in 1989. During the past two
years the Safety Board has completed investigations on at least
seven other train accidents in which a two-way end of train device
would have probably prevented an accident on a runaway train.
The Safety Board also believes that the accidents that took place
on the Burlington Northern Santa Fe Railroad at Cajon Pass, California;
the Burlington Northern Santa Fe Railroad at St. Paul, Minnesota;
and possibly, the Southern Pacific Railway Tennessee Pass, Colorado
accident could have been prevented had a working two-way end of
train device been in place.
At one time, all of Americas freight trains were equipped with
a caboose. The conductor and brakeman rode in the caboose and
performed certain safety functions. Their duties included monitoring
a pressure gage in the caboose and radioing the engineer when
the brakes at the end of the train were applied or released. They
were also required to watch out for dragging equipment and hot
journal boxes.
Each caboose was also equipped with a conductor's emergency brake
valve. If there was a problem or hazardous condition involving
the train, the conductor had the option of venting the brake pipe
air through the conductor's emergency brake valve and applying
the brakes in emergency from the rear of the train.
Technology in the form of dragging equipment detectors, hot box
detectors, and end of train devices took the place of the conductor
when the caboose was removed from freight trains. One-way end
of train devices monitored the brake pipe pressure at the end
of the train and transmitted that information directly to the
engineer by radio signal. In this manner, the engineer could read
the brake pipe pressure at the rear of the train himself and determine
if the brakes were applied or released. What was lost when cabooses
were removed from service was the ability to initiate an emergency
brake application from the rear of the train.
The two-way end of train device incorporates this additional feature.
The engineer can command an emergency brake application at the
rear of the train by flipping a toggle switch in the locomotive
cab. When the toggle switch is flipped, the two-way end of train
device will open the end of the brake pipe and vent all of the
air, thus triggering an emergency brake application from the rear
of the train. Safety Board investigators believe that two-way
end of train devices are essential to the safe operation of cabooseless
trains because they offer the only effective means of stopping
a train if the train line is blocked by a turned angle cock, crimped
air hose, frozen air line, or other such circumstances. Two-way
end of train devices have been required on Canadian railroad trains
since 1987.
The Safety Board's first recommendation on two-way end of train
devices was a result of the February 2, 1989 Helena, Montana accident.
About 4:30 am mst, freight cars from Montana Rail Link Inc. westbound
train 121 rolled eastward down a mountain grade and struck a stopped
helper locomotive consist, Helper 1, in a Helena freight yard.
The locomotive consist of train 121 included three helper units
and three road units positioned at the head end of a 49-car train.
The crew members of train 121 had uncoupled the locomotive units
from the train to rearrange the locomotive consist while stopped
on a mountain grade. In the collision and derailment, 15 cars
from train 121 derailed, including three tank cars containing
hydrogen peroxide, isopropyl alcohol, and acetone. Hazardous materials
released in the accident resulted in a fire and explosions. About
3,500 residents of Helena were evacuated. Two crewmembers of the
helper struck by the runaway train were slightly injured. The
estimated damage (including clean-up and lading) as a result of
this accident exceeded $6 million.
The National Transportation Safety Board determined that the probable
cause of this accident was the failure of the crew of train 121
to properly secure their train by placing the train brakes in
emergency and applying hand brakes when it was left standing unattended
on a mountain grade. Contributing to the accident was the decision
of the engineer to rearrange the locomotive consist and leave
the train unattended on the mountain grade, and the effects of
the extreme cold weather on the air brake system of the train
and the crew members. Also contributing was the failure of the
operating management of the Montana Rail Link to adequately assess
the qualifications and training of employees placed in train service.
Contributing to the severity of the accident was the release and
ignition of hazardous materials.
The Safety Board recommended that the Federal Railroad Administration:
Require the use of two-way end-of-train telemetry devices on all
cabooseless trains for the safety of railroad operations.
The Federal Railroad Administration had incorporated language
in the "Power Brake Regulations" to address two-way
end of train device requirements. However, the same day that the
Federal Railroad Administration was holding hearings on the revised
"Power Brake Regulations," the Cajon Pass accident of
December 14, 1994 occurred.
About 5:21 am pst, on December 14, 1994, a westbound Atchison,
Topeka and Santa Fe Railway Company (Santa Fe) intermodal train,
PBHLA1-10, collided with the rear end of a standing westbound
Union Pacific Railroad Company (UP) unit coal train, CUWLA-10,
at milepost (MP) 61.55, near Cajon, California, on the Santa Fe's
San Bernardino Division's Cajon Subdivision. The two crewmembers
from the Santa Fe train were injured when they jumped from the
moving train before the collision. Two helper crewmembers on the
rear of the UP train detrained before the collision because they
had heard radio conversations among the Santa Fe crewmembers,
the train dispatcher, and UP crewmembers. As a result of the collision,
a fire broke out that burned the two UP helper locomotive units.
Four Santa Fe locomotive units and three articulated five-pack
double-stack container cars were also destroyed. Total estimated
damages were $4,012,900.
The issues examined in this accident were: Air brake testing in
mountain-grade territory; management oversight of train handling
practices; feed-valve braking; and two-way end-of-train devices.
The National Transportation Safety Board determined that the probable
cause of this accident was insufficient available train braking
force for the Santa Fe train due to an undetermined restriction
or blockage in the trainline between the third and fourth articulated
cars. The Safety Board also concluded that had the train been
equipped with a two-way, end of train device, the collision could
have been avoided because the engineer could have initiated an
emergency brake application from the end of the train.
As a result of its investigation, the National Transportation
Safety Board closed Safety Recommendation R-89-82, which was issued
to the Federal Railroad Administration on December 6, 1989, and
reissued the same to expedite implementation into the pending
power brake law:
Separate the two-way end-of-train requirements from the Power
Brake Law NPRM, and immediately conclude the end-of-train device
rulemaking so as to require the use of two-way end-of-train telemetry
devices on all cabooseless trains. (Urgent Action)
The Federal Railroad Administration took action on our recommendation,
but only after the second Cajon accident on February 1, 1996.
The Federal Railroad Administration issued an emergency order
for the Burlington Northern Santa Fe Railroad to immediately use
two-way end of train devices and obtained agreement from the major
railroads to use two-way end of train devices on all trains in
mountainous territories by the end of 1996 and on all cabooseless
trains by July 1997.Air
Brake Inspection and Testing
Air brake safety issues including inspection, testing, maintenance,
and design are safety issues in accidents involving the Washington
METRO at Gaithersburg, Maryland; the Burlington Northern Santa
Fe Railroad at Cajon Pass, California; the Burlington Northern
Santa Fe Railroad at St. Paul, Minnesota; and the Southern Pacific
Railway at Tennessee Pass, Colorado.
Air brake inspection and safety requirements are maintained by
the Federal Railroad Administration in a section of the Code of
Federal Regulations commonly known as the "Power Brake Regulations."
The recommendations issued to the Federal Railroad Administration
(FRA) regarding new or modified regulations contained under the
"Power Brake Regulations" were the result of numerous
Safety Board accident investigations. Three Safety Board accident
investigations in particular, however, provide compelling evidence
to support the Safety Boards main concern about these regulations.
These three accidents caused over $21.4 million in property damage
and resulted in several deaths and numerous injuries to train
crews, passengers, bystanders, and property owners.
The first accident was the Helena, Montana one that occurred on
February 2, 1989 and was described previously. As a result of
that accident, the Safety Board made the following recommendation
to the FRA:
Amend the road train and intermediate terminal train air brake
tests, 49 CFR 232.13, to require additional testing of a train
air brake system when operating in extreme cold weather, especially
when the feed valve setting is changed and the train will be operated
in mountain grade territory.
The second accident that led to NTSB safety recommendations on
the power brake regulations occurred near San Bernardino, California.
About 7:30 am, Pacific daylight time, on May 12, 1989, Southern
Pacific Transportation Company freight train 111, which consisted
of a four-unit locomotive, 69 hopper cars loaded with trona, and
a two-unit helper locomotive on the rear of the train, derailed
at milepost 486.8. The entire train was destroyed as a result
of the derailment. Seven homes located in the adjacent neighborhood
were totally destroyed and four others were extensively damaged.
Of the five crew members on board the train, two on the head end
of the train were killed. A third crewman on the head end received
serious injuries, and two crewmen on the rear end of the train
received minor injuries. Of eight residents in their homes at
the time of the accident, two were killed and one received serious
injuries as a result of being trapped under debris for 15 hours.
Local officials evacuated homes in the surrounding area because
of a concern that a 14-inch pipeline owned by the Calnev Pipe
Line Company, which was transporting gasoline and was located
under the wreckage, may have been damaged. Residents were allowed
to return to their homes about 24 hours after the derailment.
About 8:05 am, on May 25, 1989, 13 days after the train derailment,
the 14-inch pipeline ruptured at the site of the derailment, released
its product, and ignited. As a result of the releases and ignition
of gasoline, two residents were killed, three received serious
injuries, and 16 reported minor injuries. Eleven homes in the
adjacent neighborhood were destroyed, three received moderate
fire and smoke damage, and three received smoke damage only. In
addition, 21 motor vehicles were destroyed. Residents within a
four-block area of the rupture were evacuated by local officials.
Total damages as a result of the train derailment and pipeline
rupture exceeded $14 million.
The National Transportation Safety Board determined that the probable
cause of the train derailment on May 12, 1989, was the failure
to determine and communicate the accurate trailing weight of the
train, failure to communicate the status of the train's dynamic
brakes, and the Southern Pacific operating rule that provided
inadequate direction to the head-end engineer on the allowable
speed and brake pipe reduction down the 2.2-percent grade.
As a result of the San Bernardino accident, the Safety Board made
two recommendations regarding dynamic brakes:
Study, in conjunction with the Association of American Railroads,
the feasibility of developing a positive method to indicate to
the operating engineer in the cab of the controlling locomotive
unit the condition of the dynamic brakes on all units in the train;
and
Revise the regulations to require that if a locomotive unit is
equipped with dynamic brakes that the dynamic brakes function.
The Safety Board feels very strongly that dynamic brakes should
be operational when locomotives are dispatched. Dynamic brakes
are an extremely important tool for train handling. Engineers
are taught to control the speed of their train through throttle
modulation and the use of the dynamic brakes. Engineers are also
taught that dynamic brakes are the "first" brake to
be used when slowing a train. Therefore, dynamic brakes should
be considered primary safety devices which must work properly
when a locomotive is dispatched.
The third accident the Safety Board investigated that led to recommendations
about the power brake regulations was the Palatka, Florida accident.
At 11:25 am on December 17, 1991, National Railroad Passenger
Corporation train 87, operating on CSX Transportation Inc. track,
derailed at milepost A697.6 in Palatka, Florida. Train 87 consisted
of a locomotive and eight cars. The locomotive and first six cars
derailed. The derailment occurred while train 87 was negotiating
a six degree six minute curve to the right (west). The derailed
equipment struck two homes and blocked the street north of the
Palatka station. Eleven passengers sustained serious injuries
and 41 received minor injuries. Five operating crew members and
four on-board service personnel had minor injuries.
The National Transportation Safety Board determined that the probable
cause of this accident was the failure of the engineer and the
fireman to maintain full attention to the train location and to
slow for the speed restriction in sufficient time to safely negotiate
the curve.
As a result of this investigation, the Safety Board recommended
to the FRA:
Amend the Power Brake Regulations, 49 Code of Federal Regulations
232.12, to provide appropriate guidelines for inspecting brake
equipment on modern passenger cars.
The Safety Board made this recommendation because the investigators
found evidence that the initial terminal brake test conducted
on the passenger cars was inadequate. The investigators felt that
the current "Power Brake Regulations" did not adequately
distinguish between passenger cars and freight cars; nor did they
take into account the different methods that needed to be used
to properly inspect each type of car.
Although an Advanced Notice of Proposed Rulemaking (ANPRM) was
issued on December 31, 1992 and a Notice of Proposed Rulemaking
(NPRM) was issued on September 16, 1994, the "Power Brake
Regulations" have not yet been revised.
Passenger Car Crashworthiness and Safety Standards
The Safety Board has been interested in passenger car crashworthiness
and passenger car safety standards for many years. The list of
accidents where the Safety Board made recommendations in this
area goes back over 25 years, from tragic accidents in Glenn Dale,
Maryland and Darien, Connecticut in 1969. The 1996 accidents on
Washington METRO at Gaithersburg, Maryland, on New Jersey Transit
in Secaucus, New Jersey, and on the MARC Train in Silver Spring,
Maryland again tragically point out the need for passenger car
safety standards.
Our past recommendations included some familiar issues:
advising passengers of emergency procedures
seat securement and luggage retention devices
safe window design
elimination of sources of direct impact injury
occupant protection
emergency exits and emergency lights
car roof escape hatches
predeparture inspection of safety devices
emergency release mechanisms for doors that are clearly identified
requirements for minimum safety standards for passenger cars
In 1985, in response to several of these recommendations, the
FRA wrote to the Board and stated that they had reported to the
U.S. Congress that, "¼the
Federal Railroad Administration concluded that passenger operations
had compiled an excellent safety record and a major Federal regulatory
effort was not necessary or warranted." Based on that response,
many of the recommendations calling for passenger car standards
were closed as "unacceptable action."
The Board then began to work with Amtrak to have its passenger
cars upgraded for occupant protection. Amtrak responded by implementing
almost all of the Board's recommendations on passenger car safety.
This approach covers only those cars used by Amtrak and does not
reach the other cars in passenger service.
The Safety Board investigated a tragic accident that occurred
in Gary, Indiana in 1993. At 9:34 am on January 18, 1993, Northern
Indiana Commuter Transportation District (NICTD) eastbound commuter
train 7, traveling from Chicago, Illinois, to South Bend, Indiana
and NICTD westbound commuter train 12, travelling from South Bend
to Chicago collided at milepost 61.1 in Gary, Indiana. Train 7
and train 12 consisted of two and three passenger cars respectively.
Train 7 passed a stop signal at Milepost 61.2 and its lead car
blocked westbound traffic where the tracks intersect. After train
12 crossed the Gary Gauntlet Bridge, it struck train 7. As a result
of the collision, 7 passengers died and 95 people sustained injuries.
The estimated damage for both trains was $854,000.
The National Transportation Safety Board determined that the probable
cause of the collision between the two NICTD trains was the inattentiveness
of the engineer on train 7, resulting in his train passing a stop
signal and partially blocking the westbound track. Contributing
to the severity of the accident was the failure of the engineer
on train 12 to take timely action to slow or stop his train before
the collision. Contributing to the severity of the injuries was
the breach of the passenger compartments in the lead cars of both
trains.
The major safety issues discussed in this report are the attentiveness
of the engineers and the crashworthiness of self propelled passenger
cars in corner to corner collisions.
As a result of this accident, the National Transportation Safety
Board issued safety recommendation R-93-24 to the Federal Railroad
Administration:
In cooperation with the Federal Transit Administration and the
American Public Transit Association, study the feasibility of
providing car body corner post structures on all self propelled
passenger cars and control cab locomotives to afford occupant
protection during corner collisions. If feasible, amend the locomotive
safety standards accordingly.
Currently, there are no Federal industry-wide standards in the
Railroad industry or in the Rail transit industry for the design
and construction of railroad passenger cars, other than an FRA
requirement for 4 emergency exits on each car and for non-breakable
glass in the windows.
In its February 20, 1996 Emergency Order, the Federal Railroad
Administration required commuter and passenger railroads to ensure
that emergency window exits actually open and operate as intended
in emergencies and that they are clearly marked and visible both
inside and outside the coach.
In the order, the Federal Railroad Administration describes a
related rulemaking required by Congress that will lead to rules
on passenger equipment safety standards. The rules will cover
many of the issues recommended by the Safety Board over the years
including: crashworthiness, emergency lighting, operation of doors,
roof hatches, passenger car interiors, and on-board emergency
equipment. The FRA has indicated that they expect to issue an
Advanced Notice of Proposed Rulemaking (ANPRM) in the next few
months with final rules due by 1997. The Federal Transit Administration
and the American Public Transit Association is working with the
Federal Railroad Administration group. It is unclear at this time
how these new standards will effect rail transit cars not currently
under FRA jurisdiction.
Conclusion
The Safety Board appreciates the opportunity to discuss Railroad
Safety issues with the committee. Our visit, however, has been
short and there has only been time to discuss the issues of the
hour which are related to these recent tragic accidents. We hope
to eventually have the opportunity to talk to the committee about
other important railroad safety issues such as grade crossing
safety, locomotive conspicuity, whistle bans, track safety standards,
engineer fatigue and hours of service, and crashworthiness of
locomotives, locomotive fuel tanks, and locomotive event recorders.
In its continuing investigations, the Safety Board has frequently
encountered recurring safety issues. Those with the authority
to regulate the railroad and rail transit industry have numerous
rulemaking initiatives in progress. It seems, however, to take
a very long time to complete these rulemakings. In the meantime,
the Safety Board continues to investigate tragic accidents where
appropriate safety regulations could have prevented the accident.
The Federal Railroad Administration has issued several emergency
orders in response to the recent Cajon Pass, California accident
and the Silver Spring, Maryland MARC Train accident. The Safety
Board has not completed either one of these investigations and
is therefore, not in a position to determine if these emergency
orders are appropriate or if they will be fully effective in addressing
the safety issues related to these specific accidents. A number
of the actions covered in the Federal Railroad Administration's
Emergency Order, however, do address Safety Board recommendations
made many years ago.
The Safety Board believes that safety regulations are sometimes
necessary to ensure that a consistent level of safety is maintained
throughout the railroad and rail transit industries. Voluntary
compliance to safety bulletins is admirable, but in the long term,
voluntary compliance can be set aside as management styles and
business conditions change.
The Safety Board encourages the Federal Railroad Administration
and the Federal Transit Administration to take all necessary actions,
not just through emergency orders, but through rulemaking as well.
Completion of rulemaking processes on Two-way End of Train Devices,
Power Brake Regulations, Passenger Car Safety Standards, Track
Safety Standards, and other activities are vital to the safety
of railroad employees, passengers, and the public. The NTSB encourages
the FRA to complete these activities as quickly as possible. The
FRA should consider the safety ramifications of further delay
and establish a plan to complete these rulemakings to save Americans
from death or injury in future railroad accidents.
The recent accidents have been tragedies. It would be an additional
tragedy if we do not seize this window of opportunity and move
forward with a sense of urgency to make the safety improvements
necessary to make our rail system as safe as it can be. We at
the Safety Board believe that now is the time for all interested
parties to act decisively on behalf of safety.
