Kostner, formerly known as Kildare, is an 'L' station on the CTA's 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. During reconstruction in 2003, its primary entrance was moved one block west to Kostner Avenue and the Kildare entrance became an auxiliary entrance.
