WMATA - Washington Metropolitan Area Transit Authority MARC - Maryland Rail Commuter Service (MD MTA)
WMATA operates regional rapid rail and bus services throughout the Washington Metropolitan area, including Montgomery County.  WMATA services provide the backbone of the County's transit system, with 12 Red Line stations providing 11,000 parking spaces.  Metrorail stations are served by 150 Metrobuses and 220 County RIDE ON buses. Each day, 130,000 riders use the stations in our County.

In mid-2000, the County began construction of a 2100-space garage at Shady Grove station with completion anticipated for late 2001. A 1500-space garage is also planned for the Grosvenor-Strathmore station.  Construction is expected to begin in 2001.

MARC service is the commuter rail component of the transit system, with 16 trains a day. Service originates in Martinsburg, W.V. or Brunswick, MD, with stops at 10 stations in our County before reaching D.C.'s Union Station.

MARC is Maryland-funded. The County supports MARC by providing parking or bus service to seven of the stations and coordinating with the State on train service issues.
