Amtrak has notified MARC Train that construction work will begin on a new HVAC system at Washington Union Station. The work will take place each day from 10:00pm to 5:00am. During this time, Gates A and B at Union Station will be closed to passengers. MARC Train 452 (10:40pm departure from Union Station) will board at Gate C or D each evening. In addition, customers detraining from Train 453 (9:25pm departure from Penn Station) should follow signage to enter Union Station. Customers boarding train 452 should allow a couple of extra minutes to get to the boarding gate and board the train.
Thank you for riding MARC Train.
