The train operator has admitted to dozing off just before the crash. It is a wonder
people weren't killed in the accident:
The NTSB has said it is reviewing footage from 41 cameras inside the station, as well as more cameras on board the train.
The damaged train was still sitting atop the escalator Wednesday morning as the National Transportation Safety Board continued its investigation. A six-man team has been sifting through the wreckage for evidence, and has been removing cameras and event recorders from the train to figure out exactly what went wrong.
NTSB lead investigator Ted Turpin has said an automatic stopping system on the train activated as it was pulling into the station at 25 mph around 2:50 a.m. Monday, applying the train’s brakes, but that didn’t stop it from smashing through a bumper post, and barreling up the escalator.
More than 30 people, including the train operator, were injured in the crash.
