Accident Report Detail

Rear End Collision of Metro-Dade Transportation Administration Trains Nos. 172-171 and 141-142

Executive Summary

About 11:35 p.m. on June 26, 1985, Metro-Dade Transportation Administration (MDTA) nonrevenue test train No. 172-171 struck the rear of MDTA revenue train, No. 141-142, which was stopped on track 2 about 1,927 feet south of the Northside Station interlocking in Miami, Florida. Neither train was derailed. Test train No. 172-171 was returning northbound after completing a southbound test run. Twelve passengers and four MDTA employees were taken to nearby hospitals where they were treated and released. The MDTA estimated the damage to be $1.6 million.

Probable Cause

The National Transportation Safety Board determines that the probable cause of this accident was the failure of the rail attendant of train No. 172-171 to follow Metro-Dade procedures by operating the train with the ATP system bypassed and his failure because of inattention, distraction, or the effects of drugs, to monitor the track ahead of the train, perceive the standing train, and react in time to stop his train safely. Contributing to the cause of the accident were flawed transit system procedures which resulted in the testing of trains with known equipment defects on the same track with revenue passenger trains.
