Amtrak and SEPTA trains in the Philadelphia area stalled by a power infrastructure problem have been restored to service.
Service on Amtrak's Keystone Service line was suspended shortly before 9 a.m. due to problems with the infrastructure supporting the overhead power system, Amtrak said in an alert. Amtrak issued a second alert just after 9:30 a.m. that Keystone Service had been restored, but with delays.
SEPTA trains on the Paoli-Thorndale Line, which share the tracks, were also affected by the problem, but were restored shortly before 11 a.m., according to a tweet sent by SEPTA.
