Car Barn

The Georgetown Car Barn, historically known as the Capital Traction Company Union Station, is a building in the Georgetown neighborhood of Washington, D.C., in the United States. Designed by the architect Waddy Butler Wood, it was built between 1895 and 1897 by the Capital Traction Company as a union terminal for several Washington and Virginia streetcar lines. The adjacent Exorcist steps, later named after their appearance in William Friedkin's 1973 horror film The Exorcist, were built during the initial construction to connect M Street with Prospect Street.

Intended for dual use as a passenger station and as a storage house for the streetcars, the Car Barn began Washington's only cable car system. Almost immediately after the building opened, the system was electrified, and the Car Barn was converted to accommodate electric streetcars. Throughout its history as a terminal and storage facility, the Car Barn was never utilized to the extent anticipated by its construction.
