The Maryland Rail Commuter service (MARC) offers commuter service to Union Station in Washington, DC.

Directions to Ft. McNair utilizing the MARC:

Take the MARC to Union Station.  Deboard the MARC train and proceed to the Metro subway.  Take the Metro Red Line toward Shady Grove and deboard at Metro Center.  Board the Orange Line toward New Carrollton or the Blue Line toward Addison Road.  Deboard the Metro at L'Enfant Plaza.  The following two options are available.
 

• Option one, the DC Metro has a stop within strenuous walking distance of Fort McNair: Board the Green Line at L'Enfant Plaza toward Branch Avenue.  Deboard at Waterfront-SEU. The station exit is in front of a Safeway store on the north side of M Street. Cross M Street and walk down 4th Street. After several blocks, the road curves to the left and becomes P Street. The first right turn takes you to the Fort McNair gate.

• Option two, upon arrival at the L'Enfant Plaza stop, deboard and proceed to either the Federal Office Building (FAA) - 10A (FOB 10-A) or to the Department of Transportation Headquarters Building (HQ Bldg.).  The DOT Shuttle stops at either location.  You must present a government ID to board the Shuttle.  Take the DOT Shuttle to the Coast Guard Headquarters Building (CGHQ), and walk Westward toward the side Ft. McNair Gate (must have a Proximity Card for entrance), or to the front Fort McNair gate (without Proximity Card).
