NEW HAVEN, Conn. (AP) -- Amtrak is providing alternate service after a freight train derailment in the New Haven area forced service to be suspended along the busy New York-to-Boston corridor.

Trains from New York's Penn Station will run to New Haven and detour to Boston's South Station via Springfield. Passengers should allow several hours of extra time.

For passengers traveling south to New York Amtrak will pick up passengers at Kingston, R.I, Providence, R.I., and Route 128 and return to Boston to board a special train to New York.

The rail service says crews were working Sunday to clear the tracks.

Amtrak service between New York and Washington is not affected and the Springfield, Mass., shuttle will operate as scheduled.
