[3] The interurban Aurora Elgin and Chicago Railway (AE&C) began service on August 5, 1902, and included a station on Oak Park Avenue.
[1] The Garfield Park branch, operated by the Metropolitan West Side Elevated Railroad since 1895, abutted the AE&C at 52nd Avenue; on March 11, 1905, the branch assumed local service west to Des Plaines Avenue in exchange for the AE&C going downtown.
The AE&C and its successor, the Chicago Aurora and Elgin Railroad (CA&E), continued to maintain westbound-only express service at Oak Park.
The station consists of a single island platform to the south of the Eisenhower Expressway with an entrance at each end.
