Great Falls and Old Dominion Railroad

The Great Falls and Old Dominion Railroad (GF&OD) was an interurban trolley line that ran in Northern Virginia during the early 20th century.

[3] From Georgetown, the railroad crossed the Potomac River on a superstructure built on the upstream side of the old Aqueduct Bridge to Rosslyn in Arlington, where it made connections with an older electric trolley line, the Washington, Arlington & Falls Church Railway (see Northern Virginia trolleys).

[4] From Rosslyn, the railroad traveled northwest along the north side of Lee Highway (now part of U.S. Route 29) to Cherrydale and then on its own right-of-way (now Old Dominion Drive, Virginia State Route 309) in Arlington and Fairfax Counties through forests, farmland and fruit orchards, bypassing the existing villages of Lewinsville and Langley.

The station at Chain Bridge Road became a focus for development that evolved into the community of McLean, Virginia.

In 1935, Fairfax and Arlington counties obtained the right-of-way west of Thrifton Junction in settlement of delinquent taxes.
