There will be a significant Penn Line schedule change on Monday, April 29. Upcoming Amtrak construction projects along the heavily-traveled Northeast Corridor between Baltimore and Washington, D.C. will impact MARC Penn Line service. Amtrak's planned construction work will require complete track closures from 11:15 p.m. to 5:00 a.m. and is expected to continue through November 2024. As a result, the following weekday MARC Penn Line schedule changes will be necessary:

Morning service to Washington Union Station

--Train 401 (4:15am departure from Baltimore to Washington) will not operate.

--Train 403 (4:40am departure from Baltimore to Washington) will operate 20 minutes later.

Late evening service, Monday-Thursday

--Train 453 (9:35pm departure from Baltimore to Washington) will depart 50 minutes earlier at 8:45pm and be renumbered to Train 455.

--Train 452 (10:55pm departure from Washington to Baltimore) will depart 50 minutes earlier at 10:05pm and be renumbered to Train 454.

Late evening service, Fridays

--Trains 453 and 452 will maintain their current schedules on Fridays only.

There are additional schedule changes to other trains. Full information, including links to download copies of the timetable, is on the MTA website at https://www.mta.maryland.gov/marc-penn-apr2024 . Printed copies are being distributed this afternoon to stations.
