NEW YORK (AP) — Authorities say a Metro-North passenger train derailment in New York City has caused multiple fatalities and dozens of injuries.

Metropolitan Transportation Authority spokeswoman Marjorie Anders confirmed the fatalities in Sunday morning's crash in the Bronx but couldn't give a number. She says the big curve where the derailment occurred is in a slow speed area.

Anders says the black box should be able to tell how fast the train was traveling.

The crash happened near the Spuyten Duyvil station. The southbound Hudson Line train had left Poughkeepsie (poh-KIHP'-see) at 5:54 a.m. and was due to arrive at 7:43 a.m. at Grand Central Terminal.

The MTA says four or five cars on the seven-car train derailed about 100 yards north of the station on a curved section of the track.
