The owners gave their own names to two stations located at the railroad's crossings of major roads: McLean Station at Chain Bridge Road (Virginia State Route 123) and Elkins Station at Old Georgetown Pike (Virginia State Route 193). The station at Chain Bridge Road became a focus for development that evolved into the community of McLean, Virginia.
In 1911, McLean and Elkins incorporated the Washington & Old Dominion Railway (W&OD) and in 1912, the new W&OD signed a 50-year lease on the Southern Railway's Alexandria-Bluemont line. In the same year, it then constructed a double-tracked Bluemont Division connecting line that traveled between two new junctions in Arlington: Bluemont Junction on the Alexandria-Bluemont line and Thrifton Junction on the Georgetown-Great Falls line. The Georgetown-Great Falls line became the Great Falls Division of the W&OD, sharing trackage with the W&OD's Bluemont Division between Rosslyn and Thrifton Junction. In 1935, Fairfax and Arlington counties obtained the right-of-way west of Thrifton Junction in settlement of delinquent taxes. Most of the right-of-way was converted into Old Dominion Drive.
The right-of-way west of Thrifton Junction became Langston Blvd (formally Lee Highway) and Old Dominion Drive; and the right-of-way between the Key Bridge and Thrifton Junction became Interstate 66. The trestle over Difficult Run lasted until 1979, when it was replaced because it could not handle the loads required of it.[6]
Great Falls Trolley Park became Great Falls Park, part of the National Park Service.
Several area names, like the town of McLean, also remain.
The GF&OD and W&OD stopped at a passenger shelter from 1904 to 1923. The W&OD terminated behind a passenger station on Fort Myer Drive from 1923 to 1938. The railroad terminated near a maintenance shop in the present route of I-66 a short distance west of Fort Myer Drive from 1938 to 1964. All of the Rosslyn stations and termini were near the present site of the Key Bridge Marriott Hotel. Historical Marker: Rosslyn Station[10]
