Built in 1887 by the Pennsylvania Railroad, it was listed on the National Register of Historic Places in 1998 as the Ada Pennsylvania Station and Railroad Park.

[1] It is a wooden building, set on a stone foundation and topped with an asphalt roof.

[3] Founded as a railway town, Ada grew quickly after the establishment of Ohio Northern University in the city in the 1880s.

Consequently, this station was built to accommodate increased passenger traffic; its Stick-Eastlake architecture is unusual for Pennsylvania Railroad depots, and it is larger than most stations built to serve small communities.
