The Norfolk Southern Railway and its predecessors have donated three cabooses for display along the W&OD Trail.
 While none of these resemble the cabooses that once travelled along the route of the W&OD Railroad, two of the three cars house exhibits of materials relating to the W&OD Railroad and Trail.

A Southern Railway bay window caboose (number X441) within the Bluemont Junction Railroad Display in Arlington exhibits photographs, maps and other information related to the County's railroads and trolleys.
Staffed by a County park ranger, the caboose is open to the public on weekend afternoons from the Memorial Day weekend through Labor Day.
The display also contains outdoor signage and photographs that describe and illustrate the history of the W&OD Railroad and of its junction that once operated at the site of the exhibit, as well as a metallic crossbuck and a metallic marker post that was once located 1 mile (1.6 km) from a station.

A cupola caboose near the Trail in Vienna Centennial Park contains a museum that houses materials that the W&OD Railroad once used.
Staffed by members of the Optimist Club of Greater Vienna, bearing on its sides the name "WASHINGTON & OLD DOMINION RAILROAD" and numbered 503, the caboose is open to the public during the afternoons on selected weekends and holidays.
Near the caboose is a historical marker, an NVRPA information sign, a metallic crossbuck on a wooden post and a metallic marker post that was once located 1 mile (1.6 km) from a station.
 A metallic white railroad whistle post with black markings is located in Vienna Centennial Park on the north side of the Trail between Church Street NE and the caboose.

Adjacent to the Trail in Vienna, the Freeman Store houses a museum of the town's history.
