NTSB: Communication error led to UWS train crash
The NTSB has revealed that a communication breakdown likely led to the Upper West Side subway collision that injured at least 20 people in a preliminary report on Thursday.
NEW YORK - The NTSB has released its preliminary report into the derailment of a 1 train earlier this month that left 22 passengers and 3 crew members injured.
In the incident, a disruptive passenger vandalized a subway train on the Upper West Side, causing the crew to stop the train and leading to a low-speed crash between trains.
According to the NTSB, the crash happened due to a communication breakdown. As the 1 train approached the 96th Street Station, radio communication was lost between the train's flagger and the supervisor.
That miscommunication led to the train running a red signal and colliding with another train, which was executing a track crossover.

Cleanup underway after subway train derailment
The NTSB is conducting its own investigation into the low-speed collision and derailment that injured over two dozen people on Thursday and has caused transit havoc.
The track in the area was equipped with trip-stops, which activate a train's emergency brakes if a train passes through a signal requiring a stop, but because the brakes on the first five railcars had been cut out, the emergency brakes could not be activated by the trip-stop.
The NTSB's investigation will continue to focus on operational and communication protocols for NYC Transit and broader issues like federal requirements for railcar event recorders.
