Amtrak service between Washington and Philadelphia has resumed electrical damage temporarily shut down the train service, officials say.
"Extensive damage" to overhead wires of Amtrak's electrical system forced the rail system to stop service for about two hours on the Acela Express, Northeast Regional and other service between the two cities.
But the service was resumed at about 2:30 p.m. Delays are expected.
The damage has also halted Amtrak service between Wilmington, Del. and Baltimore.
Crews are currently investigating the extent of the damage.
MARC service has also been interrupted north of Baltimore. Commuter train service between Baltimore and Washington continues to run normally.
