MARC commuters have had a tough time Friday morning as electrical problems have stalled all traffic along the Penn Line.
The problems began shortly after 7:30 a.m. when a train broke down just north of BWI Airport due to a pantograph malfunction, according to alerts sent to MARC riders.
Amtrak also reported power problems causing a cessation of service between Baltimore and Washington, DC. Amtrak warned of delays between one and three hours.
MARC reported that train service resumed at about 12:45 p.m. Friday.
MARC has urged riders to find alternative forms of transportation, and Metro is honoring MARC tickets.
