The National Transportation Safety Board says it will take several days of investigation before it can determine what caused a commuter train derailment in New York City.

More than 100 people suffered minor injuries when a Long Island Rail Road train hit a bumping block at the end of a track at a Brooklyn station Wednesday morning.

An NTSB spokesman says the train’s event recorders have been recovered. He says the train’s engineer has undergone drug testing. Results of those tests aren’t known yet.

New York City authorities say more than 100 people suffered minor injuries when a Long Island Rail Road train hit a bumping block at a Brooklyn station.

Fire officials at the scene Wednesday said metal that appeared to be from a rail pierced the bottom of the train and the wheels lifted up. They said the crash also damaged a work area beyond the tracks.

Gov. Andrew Cuomo said the train was moving very slowly. He said it “wasn’t really a derailment.”

Eleven of the injured were taken to hospitals. Officials at the scene estimated that 600 to 700 people were on the train.

They said many passengers were standing as they prepared to get off the train.

The cause is under investigation.
