NEW HYDE PARK, N.Y. — Thirty-three people were injured, four seriously, when two Long Island Rail Road trains, one carrying about 600 people, sideswiped each other Saturday night, authorities said on Sunday.

The collision, of a maintenance train and a commuter train as they traveled eastbound, sheared chunks off the commuter train cars, several of which derailed just east of New Hyde Park station in Nassau County.

The accident trapped frightened passengers in the darkened cars for nearly an hour as rescue crews worked to free them.

“When you look at the actual damage of the situation, the silver lining is we’re fortunate that more people weren’t severely hurt,” Governor Andrew Cuomo said at a news conference at the scene of the crash on Sunday.


Behind him, three of the 12 commuter cars sat tipped at odd angles on the track, with deep gashes in the steel visible along the length of the train.

The cause of the collision, in which the maintenance train entered the track space of the commuter train, is under investigation by the National Transportation Safety Board and is not yet known.
