Forest Park was an at-grade station on the Chicago Transit Authority's 'L' system, serving as the former western terminus of the Lake Street Elevated.[1]


The station was opened in 1910 as part of an extension of the Lake Street "L" into the Chicago & North Western Railroad's Forest Park yard. The adjacent Marion station had served as the terminal of the line since 1901.[2] Passenger service was initially operated with a single track, but was expanded to two tracks by 1946. In 1962, the at-grade stations of the Lake Street "L" were moved onto the abandoned C&NW embankment, as the local stations had been abandoned since 1958. The elevation prompted the merger of the Forest Park station and the adjacent Marion station into the current Harlem/Lake station.
