The rail company says a fire between New York City and New Haven was believed to have caused power loss for trains in the area.

Trains approaching Penn Station are being moved from the area at lowered speeds using diesel-powered engines, Amtrak said, adding that there is no estimate for when normal operations will resume.

A brush fire east of New York Penn Station has spurred power outages for Amtrak trains running to and from New Haven, Connecticut, prompting lengthy delays for passengers.
