Train operator under scrutiny
San Francisco crash injured 48 people
SAN FRANCISCO – The operator of a light-rail train that crashed and injured dozens of passengers in San Francisco came under scrutiny Sunday as federal investigators tried to figure out why he inexplicably turned off the automatic controls moments before the collision.
National Transportation Safety Board investigator Ted Turpin did not know why the operator switched the controls from automatic to manual in a tunnel near the West Portal Station.
Had he kept the autopilot on, the train would have slowed down before arriving at the station and likely not careened into a parked train while going 23 mph, Turpin said. He added that the operator never engaged the emergency brake.
The crash injured 48 people, four seriously. None of the injuries were life-threatening.
Two Los Angeles-based NTSB investigators are working with transit officials to interview passengers, witnesses and focus on assessing the condition of the train tracks, signal systems and the structural integrity of the train cars involved. Also, investigators had not finished looking at whether the signaling system played a role.
A chaotic scene unfolded Saturday after the westbound train rear-ended the other train at a boarding platform. Rescue crews hurried to the scene and removed bloodied passengers, and the operator was pinned inside his damaged compartment, said San Francisco Fire Lt. Ken Smith.
“He was in the front of the train, and part of it was pushed into him,” Smith said. “Rescuers had to pry open the doors to get to him and assist him out of the light rail vehicle.”
Neither Turpin nor local transit officials would identify the driver, but said he started as a San Francisco bus driver in 1979 and switched to light rail in 2007.
The driver was hospitalized after the crash and a drug test had been administered, which is standard procedure for crashes.
Investigators still need to interview the operators to determine the cause. Turpin said a mechanical inspection of the train that caused the accident has so far not uncovered any problems.
