The Bridgeport Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. state of West Virginia. The line runs from Grafton west to Clarksburg[1] along a former Baltimore and Ohio Rail Road line. At its east end, the Bridgeport Subdivision becomes the Mountain Subdivision; its west end is at the Short Line Subdivision.[2] [3] It is part of the CSX Baltimore Division.
The Bridgeport Subdivision opened in 1857 as part of the Northwestern Virginia Railroad and was immediately leased by the B&O.<ref>Web site: PRR Chronology, 1857 . , March 2005 Edition It changed hands to CSX through mergers.
