PHILADELPHIA (CBS) — Amtrak service was slowly getting back to normal on Saturday, a day after a powerful nor’easter forced it to come to a halt along the Northeast Corridor.

Amtrak resumed service on modified schedules between Washington, D.C. and New York City, but warned travelers to expect significant residual delays as work continues to restore full service following the storm.

Amtrak Keystone Service (New York – Philadelphia – Harrisburg) was also operating on a modified service plan.

However, Amtrak said significant delays at the height of the nor’easter led to the cancellation of Saturday’s Amtrak Auto Train service in both directions. Service was expected to resume Sunday between Lorton, Va., and Sanford, Fla. (Trains 52 & 53).
