Although the branch had originally been constructed starting from 1896 by the Metropolitan West Side Elevated Railroad Company, it did not reach Oak Park until March 16, 1924, by which time the Metropolitan had been subsumed by the Chicago Rapid Transit Company (CRT).

Plans to extend the branch as far west as Harlem Avenue were made by the Metropolitan but were never done as development never justified it.

The terminal building itself was a simple clapboard frame structure with a peaked roof on an island platform, with the tracks on either side ending abruptly.

[1] The Chicago Transit Authority (CTA) assumed operations of the "L" in 1947, and sought to streamline.

Berwyn and adjacent Cicero sued the CTA and got an injunction to stop the branch reduction, but the matter was resolved in the CTA's favor and the branch was cut back to 54th/Cermak on February 3, 1952.
