Kostner is a station on the Chicago Transit Authority's 'L' system, serving the Pink Line. It is located in the K-Town neighborhood of the North Lawndale community area, often just referred to as Lawndale. Kostner station was originally opened as Kildare Station. During reconstruction in 2003, the station was renamed Kostner because the primary entrance was moved one block west to Kostner Avenue and the Kildare entrance became an auxiliary entrance.
Kostner has the lowest ridership of any station on the L, serving only 500 people on an average weekday.
