MARC Train will operate full service on all three lines today except for Penn Line Trains 401 and 400 (4:05am departure from Penn Station and 5:40am departure from Washington) which will not operate. Penn Line Train 413 (6:45am departure from Penn Station) is also cancelled due to mechanical issues.

Please follow our winter weather guidelines for traveling tomorrow:

--Allow ample time to drive to the station, park your car, and WALK -- don't run -- to the train platform. Black ice is also likely on roads as you drive to your station, so leave early and allow extra travel time.

--We strongly encourage passengers to wear shoes appropriate for winter weather. Dress shoes and heels are strongly discouraged.

--MARC Facilities staff will be out treating platforms and parking lots, but given the extreme cold temperatures some spots may be still be slippery. WALK slowly and take your time.

--When boarding your train, use handrails to walk through wet or slushy areas. Despite treatment and cleaning, train stairs and floors can be slippery.

Trains may experience delays due to severe weather warnings, downed trees, and other severe weather-related issues. We thank you in advance for your patience and understanding -- MARC Train, Alstom, Amtrak, and CSX Transportation's top priority is to get you to your destination safely. Further updates on service will be provided as conditions warrant.
