PHILADELPHIA - Amtrak is working to restore Northeast Corridor rail service between New York City and Philadelphia. But service is expected to remain to be suspended through Monday.

Service was suspended after a train derailed in Philadelphia on Tuesday night, killing eight passengers and injuring more than 200.

New Jersey Transit is honoring Amtrak tickets between Trenton and New York. SEPTA's West Trenton line also is honoring Amtrak tickets.

Amtrak trains on Friday resumed running as scheduled between New York and Boston. However, modified service continues between Washington and Philadelphia through Monday.

New Jersey Transit has resumed service on the Atlantic City Rail Line between Philadelphia and Cherry Hill.

Trains started running again Friday beginning with the 4:33 a.m. departure from Atlantic City and the 5:37 a.m. train from Philadelphia's 30th Street Station.
