MARC service was snarled Thursday morning due to fallen trees on the tracks, and problems will continue into the Thursday afternoon and evening commute, officials said.

More than 800 MARC riders were delayed for several hours, according to the Maryland Transit Administration. Passengers from the three affected trains were taken to Gaithersburg and directed to a  bus that took them to the Shady Grove Metro station so that they could continue on to the District.

While crews continue to clear the debris, which authorities blamed on the pounding winds and heavy rain that fell Wednesday night and into early Thursday morning, issues will remain for the commute home.

MARC trains 875 (4:25 p.m. departure from Union Station) 879 (5:40 p.m. departure from Union Station) and 895 (6:40 p.m. departure from Union Station) are all canceled.

Train 877 (4:55 p.m. departure from Union Station) will run through to Martinsburg, while train 881 will make all stops between Washington and Martinsburg. Train 883 (7:25 p.m. departure from Union Station) will make all stops between Washington and Brunswick.
