Most of the Bluemont Division's passenger cars or trains ran on the W&OD Railway's Great Falls Division's line from Georgetown over the Aqueduct Bridge through Rosslyn to Thrifton Junction. From Thrifton Junction, the trains ran on the Bluemont Division's connecting line to Bluemont Junction, where they met other Bluemont Division passenger cars or trains that ran from Alexandria, following Four Mile Run in Arlington. Some of the Bluemont Division cars or trains then continued their trips through Falls Church, Vienna, Herndon, Sterling, Ashburn, Leesburg, Clarke's Gap and Purcellville to terminate in Bluemont, Virginia, at the base of the Blue Ridge Mountains, following a route that was similar to that of Virginia State Route 7.
