Southern Railway caboose. A remnant of a coal trestle stands south of the W&OD Trail, near the west end of the trail's bridge over Lee Highway (U.S. 29) in Arlington. In June 2014, the owner of a property adjacent to the regional park demolished part of the structure to provide space for a planned self-storage facility. At the time, the Arlington County government was considering a proposal to designate the structure as a local historic district. In September 2014, the Arlington County Board designated the remaining portion of trestle, which was located on NVRPA property, as a local historic district. The trestle was once adjacent to the west side of the railroad's Falls Church (East Falls Church) station, which was dismantled after the railroad closed. A white metallic marker post lettered in black with the words "Station 1 Mile" stands on the north side of the trail west of Little Falls Road near the boundary between Arlington and Falls Church. This post, which once stood next to the W&OD Railroad's tracks, is one mile (1.6 km) east of the site of the railroad's demolished West Falls Church Station. The station was located near the east side of the railroad's crossing of W. Broad Street (VA 7) in Falls Church. Near the east end of Vienna, the poured concrete abutment of a bridge that carried an interurban trolley line, the Arlington & Fairfax Railway, over the W&OD Railroad remains on the north side of the trail. An inscription showing the month and year of the abutment's construction (July 1904) is visible on the structure's east side. The trail crosses Goose Creek in Loudoun County on a span that NVRPA built on top of the piers and abutments of the highest and longest () bridge that the railroad constructed within the present boundaries of the regional park. Visitors can view these remnants and the intact span, pier and abutments of the railroad's deck girder bridge over Sycolin Creek from unpaved paths that travel between the streams in NVRPA's Two Creeks Trail Area on the north side of the trail. The Sycolin Creek bridge bears the only remaining span that once carried trains of the W&OD Railroad. As the trail travels on the concrete deck of the bridge, visitors can only see the span and the structures below if they leave the trail.
