[6] The current station is a modern structure built in 1943 by Lester C. Tichy (1905–1981) for the Pennsylvania Railroad,[7] It contains a 1960s-style pedestrian tunnel, with one of the entrances located at the former north station house.

Aberdeen was also served by an 1886-built Baltimore and Ohio Railroad station along what is now the CSX Philadelphia Subdivision just north of this one on West Bel Air Avenue.

It was removed after Amtrak completed the Northeast Corridor Improvement Project and replaced with an overpass.

MARC Penn Line service was extended to Perryville on May 1, 1991, with intermediate stops at Aberdeen, Edgewood, and Martin State Airport.
