Service has been restored on SEPTA Regional Rail lanes that were plagued by downed wires and power issues Wednesday morning.
Trains had been halted on the Airport Line and part of the Media/Elwyn Line since about 7:15 a.m., but began operating again at about 10:45 a.m.
Earlier, the Wilmington/Newark Line was also briefly suspended. The Airport Line problems prompted the transit agency to run shuttle buses between 30th Street Station and Philadelphia International Airport.
SEPTA said some continued delays may occur as service resumes.
