Rare surviving examples of a once commonplace small-scale railroad junction, these three frame structures served as the Pennsylvania Railroad’s depot complex at the Washington and Popes Creek branches. The two-story interlocking tower housed the critical function of controlling all the signals and switches in the vicinity of the Bowie junction. The tower, a waiting shed, and a combination freight and passenger building were moved approximately fifty feet from the active Amtrak right-of-way and preserved by the City of Bowie as a small community museum highlighting the local role of the railroad.
