(CNN) -- Amtrak service was restored on Wednesday morning between Baltimore and Philadelphia after repairs to the overhead wire system near Wilmington, Delaware, were completed, the rail agency said.
Power problems led to the temporary suspension of service on the Northeast Corridor between the cities. The disruption occurred at 7 a.m. EST on Wednesday -- just ahead of morning rush hour.
Passengers should expect residual delays of 15 to 20 minutes through the affected area, Amtrak said.
Steve Kulm, an Amtrak spokesman, earlier said that the power problems had also forced delays for scheduled service in and out of Union Station in Washington.
