An Amtrak Acela derailed as it left New York's Penn Station at a slow speed during Friday morning rush hour and all 248 passengers were safely evacuated, Amtrak said.
The service disruption continues to affect a busy commuting hub for the New York metro area into the afternoon commute.
The transportation agency referred commuters to their website for the latest information.
The Acela Express train, which originated in Boston and was heading to Washington, derailed around 9 a.m.
"The rear of the train was still on the platform, and all 248 passengers have exited the train onto the platform and into the station safely," Amtrak spokeswoman Kimberly Woods said in a statement.
