MARC trains running late

5:20 p.m. Update: Transit officials say MARC Train 850 will leave Washington 10 to 15 minutes late.

4:45 p.m. Update: Camden Train 853 will be late. The Maryland Transit Administration says a freight train is blocking the switch leading to Union Station.

3 p.m. Update: The special Camden Line train is operating about 25 minutes late.

9:15 a.m. Update: Maryland transit officials have made several changes for Friday in anticipation of an increase in commuter rail traffic around midday as people get out of Washington for the holiday:

-- Camden Line Train 852, which normally departs Washington at 5:51 p.m., will not operate. As an alternative, a train will depart at 2 p.m. making all of the Camden stops.
-- Larger trains are scheduled to operate on the midday Penn Line trains.
-- Brunswick train 871 will operate according to schedule, but the train will have more cars to accommodate additional passengers.

Original post: MARC Brunswick Line train 892 is running about 12 to 15 minutes behind as it approaches Germantown. This is owing to a minor mechanical problem.
