The WB&A Terminal in Baltimore, now a former westside downtown Baltimore  bank branch for the old Equitable Trust Company at North Liberty Street and Marion Street (alley)
The Scott Street electric generating power substation on the NE corner of Scott and West Ostend Streets in southwest downtown
The Westport tunnel's southern portal is visible just north of the Baltimore-Washington Parkway's Annapolis Road exit.

The Baltimore Light Rail built in early 1990s uses the right-of-way twice:  once from Baltimore Highlands through North Linthicum to a point north of Maple Road, and again from south of Linthicum to BWI Airport.
 The section of the Light Rail going to Glen Burnie (Cromwell Station) uses the Baltimore & Annapolis Railroad's parallel right-of-way.

Linthicum railroad station 
WB&A Boulevard in Severn was built on the right-of-way.

A section of railroad track exists in the Academy Junction section of Odenton, Maryland.
It branches off of Amtrak's Northeast Corridor just south of MD 175/Annapolis Road and travels east past the Odenton Library and across MD 170/Piney Orchard Parkway at grade before turning north to cross Annapolis Road, also at-grade.
It then travels a short distance north to the site of the old Nevamar Company's manufacturing plant.
That plant shut down in 2004 and trains haven't run on the spur since.

At the northeast corner of the location where the track listed above crosses MD 170 (Telegraph Road) is a brick building that once housed the WB&A operations headquarters.
The Baltimore-Washington main line and Fort Meade-Annapolis (South Shore) branch crossed at this location, known as "Naval Academy Junction."
The interlocking tower that controlled this crossing comprised the second floor.
Commercial office tenants occupy the building today.

Parts of the Power line Path remains in use to this day.
The single circuit 115KV path from WB&A Road (just south of BWI Airport) to Telegraph Road and Annapolis Road remains with some modifications.
Another path was replaced by a double circuit 115KV monopole from Pumphrey to Linthicum.
Both are now lines used by BGE.

The "Naval Academy Junction" shops sat about one mile (1.6 km) north of "Naval Academy Junction," on the east side of MD 170.
The brick shop buildings were subsumed into a larger building complex that housed a number of manufacturing companies, including Nevamar Plastics, but those shops were torn down in 2013.
The electrical power plant for this section of the WB&A overhead still stands, and is visible from MD 170.

Two portions of the WB&A Trail, one from Odenton Town Center to the Two Rivers development and another 5.8-mile (9.3 km) section from the Patuxent River to Glenn Dale, run on the old right-of-way of the Main Line.
 These two portions of the trail are not connected due, in part, to a property dispute that diverted the trail west in Anne Arundel County where a bridge will be built later.

The trestle over Horsepen Branch on the Bowie Race Track spur, and short sections of roadbed on either side of the trestle. (
A nearby rail trail signed "WB&A Spur Trail" branches off of the WB&A Trail and was built on a route that once served the race track, but the route was actually constructed subsequent to the WB&A's demise, by the Pennsylvania Railroad.).

MD 704 was built on the right-of-way.

A freight motor, Washington Baltimore & Annapolis #1, is maintained at the Western Railway Museum in Rio Vista, California.
