Maryland Area Regional Commuter, more commonly referred to as MARC (pronounced as a single word), is a commuter rail service operating three lines from Washington, DC to various places in central Maryland and the Eastern Panhandle of West Virginia. The three lines, from east to west, are the Brunswick Line, the Camden Line, and the Penn Line. MARC is administered by the Maryland Department of Transportation (as part of the Maryland Transit Administration), and is operated under contract with CSX Transportation and the National Railroad Passenger Corporation, or Amtrak.
