Northern Virginia trolleys

The Northern Virginia trolleys were the network of electric streetcars that moved people around the Northern Virginia suburbs of Washington, D.C., from 1892 to 1941. At its peak, the network consisted of six lines that connected Rosslyn, Great Falls, Bluemont, Mount Vernon, Fairfax, Camp Humphries, and Nauck, with two of the lines crossing the Potomac River into Washington, D.C. Two companies were founded in 1892: the Washington, Arlington and Falls Church Railway Company and the Washington, Arlington and Mount Vernon Railway.
