Rail transportation provides a convenient way to travel to or from Washington DC, and the city's system makes it easy to get around once you are here. The subway system, known locally as Metro, can be an easy way to move throughout the city, as well as regional destinations in Northern Virginia and Maryland. If traveling to DC from further away, Amtrak provides service to Union Station. Regional train systems also service the city, including VRE, servicing Virginia, and MARC, servicing Maryland.
