Brunswick Line

The Brunswick Line is a MARC commuter rail line consisting of a main line running from Washington D.C. to Martinsburg, West Virginia and a branch line from just south of Point-of-Rocks station to Frederick, Maryland. The service is operated under contract by CSX Transportation, but is administered by MARC, a service of the Maryland Transit Administration (MTA). The Brunswick Line is MARC's longest line, and operates over CSX's Metropolitan, Old Main Line, and Cumberland Subdivisions. It is the successor to commuter services provided by the Baltimore & Ohio Railroad (B&O) as long ago as the mid-19th century. In 1971, Amtrak acquired passenger service from the B&O and established the Blue Ridge line in 1973. In 1983, Maryland, along with a number of other Northeastern states, took control of its commuter railroads and the "MARC" (Maryland Area Regional Commuter) service name was established. The Brunswick Line was not acquired from Amtrak until 1986.
