Emergency rescue personnel work the scene at the site of the Metro-North passenger train derailment in the Bronx borough of New York.
Amtrak has halted service between New York City and Albany, New York, after a fatal Metro-North derailment in the Bronx.
But Metro-North says service on its New Haven line in Connecticut is not affected by Sunday's derailment on its Hudson line in New York City. Four people were killed and 63 were injured in the crash.
Amtrak spokesman Cliff Cole says the rail service is asking passengers to stand by for more information about when service will resume. Amtrak runs along the same rail line where several Metro-North cars derailed.
The Connecticut rail service runs on a line separate from the Hudson line. It extends from New Haven to Grand Central Terminal.
Amtrak says service on the heavily travelled Northeast Corridor line between Boston and Washington is also unaffected.
