Delays are expected on Northeast Corridor service between the two cities after several trains were canceled.
Thousands were left stranded overnight Wednesday between New York City and Washington D.C. due to the issue.
Action News Traffic reporter Matt Pellman said some services, including New Jersey Transit are still delayed or canceled as of 7 a.m.
Amtrak also said power is restored on one track but that there are still delays due to speed restrictions and rail congestion.
Extensive delays began just after 5:30 p.m. Wednesday when Amtrak announced downed powerlines between Newark and New York Penn Station.
