The center track is used for storage and relaying trains to the adjacent Falls Church Yard.

[2] While the station has a street address on Haycock Road, it is physically located in the median of Interstate 66 near Virginia State Route 7 (Leesburg Pike); riders access the platform and mezzanine using an elevated walkway from the parking area.

This is a suburban transfer station, as commuter buses that serve communities near the Dulles Toll and Access Roads (Virginia State Route 267) connect to the Metro system at West Falls Church using a bus-only exit from the Access Road.

With the opening of the Silver Line on July 26, 2014, many commuter bus routes that formerly terminated at West Falls Church were rerouted to instead terminate at locations along the new Silver Line stations in Tysons and Reston.

[3] West Falls Church was also the original staging point for Washington Flyer buses to Dulles Airport, but this shifted to Wiehle-Reston East with the opening of the Silver Line.
