Western is an 'L' station on the CTA'sBrown Line. It is an elevated station with two side platforms, located in the Lincoln Square neighborhood. The adjacent stations are Rockwell, which is located about one quarter mile (0.4 km) to the west, and Damen, about one half mile (0.8 km) to the east. Between Western and Rockwell the line descends and runs on surface level tracks for the rest of the route to Kimball.
The station was put into service in 1907 as part of Northwestern Elevated Railroad's Ravenswood line, and has been rebuilt twice since—in the late 1920s, and again from 1979 to 1981. The current station consists of two side platforms, and a central storage line, its platforms were extended in 2006–07 to enable the station to accommodate eight railcars.
A portion of the Berlin Wall is inside the Western Avenue CTA station in Chicago. Dedicated to the citizens of Chicago for helping "secure the freedom" of Berlin. The wall was transported to the city via Lufthansa Airlines. The Lincoln-Square Neighborhood has been historically German.
