Accident Report Detail

Collision and Derailment of Two Subway Trains Metropolitan Transportation Authority New York City Transit

Executive Summary

At 2:39 p.m. on February 9, 1995, a Metropolitan Transportation Authority/New York City Transit (NYCT) northbound M line subway train collided with the rear car of a stopped NYCT B line subway train. The collision occurred on elevated track about 1,011 feet south of the Ninth Avenue station in Brooklyn, New York. Four NYCT employees and 11 passengers sustained minor injuries.

Contributing to the collision was the design modification to the automatic key-by feature of the automatic stop arm that enabled the operator of the M train to pass a stop signal contrary to the published operating rules that require stopping at a red signal unless permission to pass is granted by Rapid Transit Operations.

Probable Cause

The National Transportation Safety Board determines that the probable cause of the rear end collision between the two subway trains was the inadequate oversight and compliance program of the NYCT to ensure that train operators comply with the published operating rules.
