Original Post:

MARC riders: All southbound Penn Line trains are going to be 5 or 10 minutes late due to a track defect. The regular southbound track is out of service between West Baltimore and Bowie. Trains will board on the center track. But the Maryland Transit Administration asks that you remain on the southbound platform until you are directed to cross the tracks.

Additionally, Camden Line train 841 is running 8 to 10 minutes late.
