Kostner is an abandoned rapid transit station in the West Garfield Park neighborhood of Chicago, Illinois.
Neighborhood residents wanted the CTA to build a replacement station at Kostner Avenue.
Eventually, the residents circulated a petition for the station's construction and threatened to sue the Department of Public Works.
The city also agreed to build the station, and the CTA did track, signaling, and electrical work.
The CTA solved this problem by creating two temporary bypass tracks around the construction site.
Where Kostner differed from the other stations, though, was in its size and design due to its expected low ridership and late addition to the system.
Since Kostner was never intended to be part of the Congress Line, the CTA put a curve in the tracks at the station site.
