Berwyn is an 'L' station on the CTA's Red Line. It is located at 1121 West Berwyn Avenue in the Edgewater neighborhood of Chicago, Illinois. The adjacent stations are Bryn Mawr, located about 3⁄8 mile (0.60 km) to the north, and Argyle, about 1⁄3 mile (0.54 km) to the south. Four tracks pass through the station, but there is only single island platform in the center of the tracks; Purple Line weekday rush hour express service uses the outside tracks but does not stop at this station. Berwyn is named for the Berwyn station in the community of the same name, which is west of Philadelphia. Many of the roads (and thus CTA stations) in the Edgewater neighborhood are named after stations on the former PRR Main Line.
The Northwestern Elevated Railroad extended its services north from Wilson to Central Street in Evanston in 1908, but they did not build a station at Berwyn Avenue until the tracks between Wilson and Howard were elevated onto an embankment between 1914 and 1922. This new station was built to a design by architect Charles P. Rawson; the date of opening is not known, but a station may have existed at Berwyn by 1917. At the time of its opening the station was named Edgewater Beach Station; the name was changed to Berwyn in the late 1950s, around about the time that Lake Shore Drive was extended from Foster Avenue to Hollywood Avenue destroying the namesake Edgewater beach.
As part of Phase I of the Red Purple Modernization, which is slated to begin as early as 2017 providing funding is secured, Berwyn and Lawrence will temporarily be closed for a period of 3 to 4 years during which time the elevated structure and stations will be completely rebuilt.
