Original Ground-Level Station

The first "L" station at Oak Park Avenue was built as part of the Lake Street Elevated's 1901 street-level extension along South Boulevard to Wisconsin (Marion) Avenue in Oak Park. The "L" was powered by overhead trolley wire along the extension for safety purposes due to the grade-level running. The tracks also paralleled the adjacent Chicago & North Western Railroad.

The modest stations on this portion consisted of island stations and platforms constructed of wood. The narrow station houses with their clapboard paneling and peaked roofs with overhanging eaves emptied out onto an island platform covered by a peaked canopy that was actually a continuation of the station house's roof. The tall steel poles that carried the "L"'s overhead wires occasionally poked through the canopy, interrupting the platform.

The "L"'s street-level operation began to result a number of crossing accidents, typically due to pedestrians and wagon drivers failing to take note of approaching trains. Neither the "L" nor the C&NW had any type of crossing protection originally. Manually-operated crossing gates and gatemen helped reduce accidents but did not eliminate them. The problem got worse as automobile traffic entered the picture and became more prevalent. The situation was further exacerbated when the parallel C&NW elevated their right-of-way circa 1908-09, creating a blind intersection due to the embankment preventing southbound traffic from seeing approaching "L" trains until they were on the crossing. The Chicago and Oak Park municipal governments tried for decades to get the "L" to elevated their tracks west of Laramie Avenue, to no avail.

 

Track Elevation

Finally, in 1961 construction began on a joint project to elevate the Lake Street "L" tracks. The $4 million project was jointed financed by the Chicago Transit Authority (who had assumed operation of the "L" in 1947), City of Chicago, Village of Oak Park, Cook County, State of Illinois, and US Bureau of Public Roads, and in cooperation with the Chicago & North Western Railroad. Rather than build a new elevated structure for the "L", the rapid transit tracks were relocated onto the C&NW's embankment, occupying the southern portion of the elevated right-of-way, which the railroad vacated. The elevation project eliminated 22 grade crossings between Laramie and Harlem avenues.

The elevation project included the construction of new stations and removal of the old wooden stations at street-level. The stations included new island platforms on the embankment and street-level station houses on the south side of the embankment. The stations were very modern for the time, and described thusly in a promotional brochure for the project:

Integrated with the south wall of the North Western embankment, the new stations incorporate many design features.

Large picture windows enhance a light and bright interior. External walls are of ceramic glazed brick in the color code for the respective station. The color is repeated in porcelain enamel panels of each station front, in the glazed ceramic tile of the interior walls, and in the porcelain enamel panels of the agents' booths.

Electric signs over the entrance of each station buildings are to identify the station and display the travel time between the station and Chicago's Loop.

Passenger control facilities include agent-controlled, illuminated fare indicator turnstiles, coin-operated turnstiles, and electrically-operated, remotely-controlled exit turnstiles.

In the metal platform canopies, which extend over the roofs of cars at train stops protecting boarding and alighting passengers from rain, sleet and snow, the station color code is repeated. Translucent fiberglass panels are interspersed with the metal panels of the canopies.

Platforms and stations are illuminated by fluorescent luminaires.

At the platforms, the lights are turned off ad on automatically by photo-electric cells. Lighting in the stations is controlled by the agents.

The "color code" for Oak Park station, used for various accents in the facility, was peach. The tiled wall outside the station entrances, on the embankment, featured pin-mounted metal letters spelling out the name of the station entrance.

The Oak Park station had two entrances, with one at Oak Park Avenue at the west end of the station and another at the east end of the station at Euclid Avenue. As a result, the station was sometimes referred to as "Oak Park-Euclid" in some promotional materials, though maps and signage simply referred to the station at "Oak Park".

The station entrances at Central, Austin and Oak Park were equipped with an escalator in addition to the stairs to access the platform. The escalators were of a reversible, dual-operation type. Typically, in rush hours the escalators operated in the peak direction (up in the morning, down in the evening) and in off-peak hours operated automatically. While in automatic mode, the escalator was activated by treadle steps, at the top and at the bottom. Once set in motion by a passenger, it operated in the proper direction until the passenger had alighted. Flashing signs warned patrons not to board an escalator operating in the wrong direction. Both the escalators and stairs were protected by glass-walled shelters at the platform level.

The platform features a wooden floor and a steel canopy supported by I-beams. The platform lights outside the canopy were unusual, found only in Oak Park suburban stations, with a thin pole and a conical head with a convex saucer as a cap.

Lake "L" trains began using the new elevated right-of-way on the C&NW embankment between Laramie and Harlem on Sunday, October 28, 1962. The ground-level stations closed and the elevated platforms opened, but the new permanent street-level station houses were not ready yet, due to the street-level tracks needing to be removed before they could be completed. Thus, on opening day, temporary fare control areas were used at Oak Park and Euclid.
