Maryland’s MARC commuter train service suspended all service and canceled several routes Friday morning due to a system-wide outage, officials said. Train service was restored more than four hours later.
Holly Arnold, administrator of the Maryland Transit Administration, said the Brunswick, Penn and Camden lines were impacted by a PTC communications issue. PTC stands for positive train control, a system that enables real-time communication sharing designed to prevent dangerous accidents, the Federal Communications Commission says.
Service on the Brunswick and Camden lines will be reduced during the afternoon. Here are details on changes for the Brunswick line and Camden line.
More than 20 trains were canceled following the service suspension.
