"Vandal-Induced Brake Failures and Lost Radio Communication Blamed for NYC Subway Collision: NTSB Report"
Vandals pulling emergency brake cords and brake failures contributed to a collision between two NYC subway trains, leaving 24 commuters injured. Federal investigators found that safety systems did not work as intended, and the MTA's procedures for handling malfunctioning trains and radio communication systems are under scrutiny. The collision occurred after a vandal tampered with the brakes, causing the train's systems to malfunction, and subsequent failures led to the collision with another train.
