Good morning Madam Chairwoman and Members of the Subcommittee.
I appreciate the opportunity to represent the National Transportation
Safety Board (NTSB) before your Subcommittee to discuss mechanical
issues in railroad accidents.
Thus far, 1996 has been a busy year for the NTSB, and a tragic
year for the railroad and rail transit industries. Since January
1, 1996, the Safety Board has launched railroad investigators
to 18 railroad accidents that resulted in 19 fatalities, 230 injuries,
and over $64 million in damages. Included in these 18 accident
investigations are 6 runaway trains, 6 collisions, 5 derailments,
and 1 grade crossing accident.
RECENT SIGNIFICANT ACCIDENTS
Occurrences since January 1 include tragic 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. These four accidents are
major accidents that involved launching 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 being investigated as regional
accidents by the Safety Board's regional accident investigators.
These accidents all involve important railroad safety issues,
and today I would like to discuss three of those issues -- two
way end of train devices, air brake inspection and testing, and
passenger crashworthiness and safety standards.
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, we have 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 the Southern Pacific Railway at Tennessee Pass, Colorado,
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 a.m. local time, 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 (FRA):
Require the use of two-way end-of-train telemetry devices on all
cabooseless trains for the safety of railroad operations.
The FRA had incorporated language in the "Power Brake Regulations"
to address two-way end of train device requirements. However,
the same day that the FRA was holding hearings on the revised
"Power Brake Regulations," the Cajon Pass accident of
December 14, 1994, occurred.
About 5:21 a.m. local time 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 Safety Board closed Safety
Recommendation R-89-82, which was issued to the FRA on December
6, 1989, and reissued the same recommendation 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 FRA did take action on our recommendation, but only after
the second Cajon accident on February 1, 1996. The FRA 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 FRA in a section of the Code of Federal Regulations commonly
known as the "Power Brake Regulations." The recommendations
issued to the 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 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 a.m., local 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 a.m., 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 to the FRA 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 a.m. 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 issued 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;
and
requirements for minimum safety standards for passenger cars.
In 1985, in response to several of these recommendations, the
FRA stated that they had reported to the U.S. Congress that, "...
the 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 a.m. 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 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.
There are currently 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.
Madam Chairwoman, we appreciate the opportunity to discuss these
important issues with the Subcommittee.
That completes my statement, and I will be happy to respond to
any questions the Subcommittee may have.
