Train engineer texted 22 seconds before fatal L.A. collision

LOS ANGELES -- A Metrolink engineer sent a cell phone text message 22 seconds before his commuter train crashed head-on into a freight train last month, killing 25 people, federal investigators said Wednesday.

Cell phone records of engineer Robert Sanchez, who was among the dead, show he sent a message after receiving one about a minute and 20 seconds before the crash, the National Transportation Safety Board said in a press release.

Investigators are looking into why Sanchez ran through a red signal and collided with a Union Pacific train Sept. 12 in Los Angeles' San Fernando Valley. It was the nation's deadliest rail crash since 1993.

Sanchez sent his last text message at 4:22:01 p.m. According to the freight train's onboard recorder, the accident occurred at 4:22:23 p.m.

Records obtained from Sanchez's cell phone provider also showed that he sent 24 text messages and received 21 messages over a two-hour period during his morning shift. During his afternoon shift, he received seven and sent five messages.

NTSB investigators were continuing to correlate times from Sanchez's cell phone, the train recorders and data from the railroad signal system.

"I am pleased with the progress of this major investigation to date," acting NTSB chairman Mark V. Rosenker said in a statement. "We are continuing to pursue many avenues of inquiry to find what caused this accident and what can be done to prevent such a tragedy in the future."
