Electrified Rail Pierced New York Train In Crash, Official Says.

Hundreds of feet of electrified rail skewered the first two carriages of a New York commuter train in a collision with a car at a railroad
crossing, a federal investigator said on Wednesday, describing the area's worst rail crash in decades.

Investigators were focused on why the car was stopped at the crossing near the suburb of White Plains north of New York City before the Metro-North train crashed into it during Tuesday evening's rush hour, pushing the vehicle about 1,000 feet down the line.

The rail broke into long pieces, penetrating the first train carriage as a fire broke out, apparently fueled by gasoline in the vehicle's fuel tank, gutted the rail car's interior, he said. At least one section of the electrified, or "third," rail also entered the second carriage near its ceiling.

"This third rail is just basically piling up inside that first train car," Robert Sumwalt, a member of the National Transportation Safety Board (NTSB), said at a news conference ahead of a week of gathering evidence and interviewing witnesses.

Sumwalt said the NTSB expected to release data from the recorder on the train on Thursday.

Five train passengers and the woman who was driving the Mercedes sport utility vehicle that was stuck on the tracks were killed. Investigators said they do not yet have an explanation for how the vehicle, which officials had earlier mistakenly identified as a Jeep, became stuck on the tracks.

Metro-North, run by the state-controlled Metropolitan Transportation Authority, had four high-profile accidents in 2013 that led to a safety assessment by the Federal Railroad Administration (FRA).
