THE BRONX - An initial investigation has revealed there may have been a pre-existing problem on the tracks which caused Thursday night’s Metro-North train derailment, a source tells News 12 The Bronx.

Service on the Hudson Line is suspended indefinitely in the Bronx after 10 out of 24 cars derailed Thursday night near the Spuyten Duyvil station. Transportation officials say that nine of the cars are still stuck on the tracks.

A source told News 12 that an initial investigation has revealed that a section of the track may have deteriorated to a point where it caused the train to go off the rail.

The MTA is offering options for people who rely on the Metro-North Hudson Line. There are limited service southbound trains from Poughkeepsie to Yonkers, where passengers can use shuttle services to get to the 1 train. For northbound service from Manhattan to Poughkeepsie, customers are urged to take the 1 train to Van Cortlandt Park. From there, travelers can take shuttle service to Yonkers for the limited Hudson line train service.

The MTA is urging people who need to get to Riverdale or Yankee Stadium to use bus service or the subway.
