The Maryland Transit Administration is warning passengers to plan for delays Monday morning on the MARC Penn Line and modified service on the light rail line as the agency operates in "storm recovery mode" following Hurricane Irene.
The MTA issued a statement saying that all of its systems will be operating for the Monday morning commute but that the Penn Line will operate a limited service schedule so certain repairs can be made by Amtrak, which operates the line for the MTA. Passengers were advised to consult the MTA website to see which trains are running and when. The MTA said the Camden and Brunswick MARC lines will have full service.
In addition, the MTA statement said, the light rail will offer its regular service from North Avenue to the Cromwell and BWI Marshall Airport stops on Monday morning. But the MTA is using buses to serve passengers who want to travel between North Avenue and Hunt Valley, because crews are working along that route to repair damage to power lines and remove fallen trees.
According to the MTA, the local bus, metro subway and Inter County Connector buses will operate on their regular schedules. Mobility service will also be available, but customers are asked to call Transit Information Services at 410-539-5000 to schedule trips.
Amtrak announced that all Acela service has been canceled Monday between Washington and Boston.
