Investigators examine train crash site after 100 people were injured

It could take days before it is known why a Long Island Rail Road train crashed at the end of a platform as it pulled into a major transportation hub, injuring 100 people, federal transportation investigators said.

The packed, rush-hour train crashed as it entered Atlantic Terminal in Brooklyn on Wednesday morning, hurling passengers onto the floor and slamming them into each other. Many had been standing as they prepared to get off the train at the last stop.
