Officials to probe train’s erratic speed just before crash

NEW YORK — Federal investigators will be looking into why a packed Long Island Rail road commuter train was travelling erratically at twice the speed limit when it crashed at a rail terminal, injuring more than 100 people.

National Transportation Safety Board investigator Ted Turpin said Thursday the train had been travelling at least 10 mph when it train slammed into the end of a platform at Atlantic Terminal in Brooklyn on Wednesday morning; the terminal’s speed limit is 5 mph.

A U.S. official briefed on the investigation said the train had erratically changed speeds in the three minutes before the crash, accelerating and decelerating between 2 and 10 mph.

The official, who was briefed on the investigation but was not authorized to speak publicly about it and spoke on the condition of anonymity, said the train was travelling at allowable speeds as it approached the station.
