Transportation in the Washington, DC metro area has a complicated organizational structure on account of the fact that the area covers two states (Maryland and Virginia) as well as the District of Columbia itself. There is one regional transportation operator, and many of the local governments in the region operate their own services as well.
The regional operator is the Washington Metropolitan Area Transit Authority (WMATA), best known as Metro. Prior to WMATA’s establishment by Congress in 1967, the area’s streetcar and bus lines were operated by various private companies. Ground was broken on the Metrorail system in 1969 and it opened on March 27, 1976. Today, Metrorail has 91 stations and 117 miles of track, with one extension under construction. Metrorail carries more passengers than any other rapid transit system in the United States except New York City, with over 217 million passengers using the system in fiscal year 2012.
WMATA also operates fixed route bus service under the Metrobus banner. Metrobus was founded in 1973 when WMATA bought out the four remaining bus companies that were still operating in the area. WMATA now operates a fleet of over 1,500 buses on over 300 routes to over 12,000 bus stops throughout the region, providing transportation to over 133 million people each year. Metrobus operates an environmentally friendly fleet with many compress natural gas, hybrid diesel electric, and clean diesel burning buses.
In addition, many of the local governments in the region, such as Montgomery County in Maryland and the City of Alexandria, operate their own bus systems within their jurisdictions in coordination with WMATA. There are also two local commuter rail systems. MARC trains operate from Union Station to Maryland and West Virginia, while Virginia Railway Express trains operate from Union Station to Virginia.
Regional transportation in the Washington, DC area is overseen by the Washington Metropolitan Area Transit Authority (WMATA). WMATA was founded in 1967, began construction on the Metrorail system in 1969, and began operating Metrobus in 1973. Today, Metrorail is the second busiest subway in the United States and Metrobus has one of the largest fleets in the country.
The DC Circulator is managed by the District Department of Transportation and WMATA and operated by First Transit. Service began in 2005 on two routes and service was gradually expanded to include five routes serving all four quadrants of the city. Circulator buses do not operate on a fixed schedule. Instead, they use a headway based schedule; each route operates every 10 minutes during its hours of operation. The service used Van Hool A300Ks and Van Hool A330s until 2015, at which time New Flyer XDE40s were introduced to the Circulator fleet.
Ride On is the county operated bus system in Montgomery County, MD. It is one of the largest medium sized transit agencies in the United States, operating over 80 routes with a fleet of over 500 buses based at three garages throughout the county. Service began on March 31, 1975. In the spring of 2000, two buses were repainted silver to commemorate Ride On's 25th anniversary. In 2015, three buses were given a special 40th anniversary wrap to commemorate that anniversary.
DASH is the bus system operated by the Alexandria Transit Company, a non-profit organization wholly owned by the City of Alexandria. It was founded in 1984 to supplement the WMATA Metrobus routes running within Alexandria. It now has 10 routes served by a fleet of over 100 buses. DASH isn't just a name, it is actually an acronym that stands for Driving Alexandrians Safely Home.
Potomac and Rappahannock Transportation Commission (PRTC) is the transportation system serving Prince William County and the cities of Manassas and Manassas Park in Virginia. PRTC operates two services. OmniRide is a commuter bus service operating from Prince William County to downtown Washington, DC and other employment centers in Northern Virginia. OmniLink is the local bus service within Prince William County, operating both fixed routes and demand-response service. PRTC was established in 1986.
MARC is MTA Maryland's commuter rail system connecting Baltimore and Washington. MARC also operates a third line to Frederick, Brunswick, and eastern West Virginia. MARC operates 93 trains a day over its three lines. Since December 7, 2013, limited Penn Line service has also been available on the weekends.
Virginia Railway Express (VRE) was launched in the summer of 1992 on two routes, connecting Washington, DC to Manassas and Fredericksburg. Service runs on weekdays only. Ridership has grown quickly since the service was launched, and VRE's fleet is now entirely multi-level in order to handle this high level of demand. Service was extended to Spotsylvania in November 2015. VRE is owned jointly by the Northern Virginia Transportation Commission and the Potomac and Rappahannock Transportation Commission.
