Metro to honor MARC tickets
Passengers should show their tickets to station managers for access.
Maryland Transit Administration officials said the delays were due to a CSX freight train that had a braking emergency west of Germantown. The train was a mile and a half long, and carrying hazardous materials. Protocol required all train traffic to stop while the conductor walked "the entire length of the train to ensure that the train had not derailed and that no hazardous chemicals had been released," the MTA said.
Once the train resumed it had a second emergency braking between Rockville and Garret Park, requiring a second inspection and suspension of train traffic.
The MTA said the train had cleared the MARC area and would not affect afternoon service.
