Official: Brooklyn train derailment investigation could take days

NEW YORK — Federal investigators said it could be days before they determine 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.

The rush hour train crashed as it entered Atlantic Terminal in Brooklyn Wednesday morning, hurling passengers onto the floor and slamming them into each other.

The front of the slow-moving train hit a bumping block, left the tracks and smashed into a small structure, apparently a work area. Authorities say a rail pierced the floor of a train car. About 100 people were treated for minor injuries.

National Transportation Safety Board investigator Jim Southworth says it will take three to seven days to investigate the accident scene before they determine what caused the crash.
