The site of Argyle station was first used as
Argyle Park station on the
Chicago and Evanston branch of the
Chicago, Milwaukee & St. Paul Railroad route, which opened on May 21, 1885. On opening, the station houses along the route were described as "attractive frame structures built in the Gothic and Queen Anne styles." The station was again rebuilt to a design by architect Charles P. Rawson when the tracks between Wilson and
Howard were elevated onto an embankment between 1914 and 1922. In 1979, the station received a $250,000 facelift and, in 1991, a
Chinese-style hipped-and-gabled roof was added to the platform canopy. The station was closed for renovation from August 24 to October 5, 2012.
Red & Purple Modernization Project As part of this project, the Argyle station was rebuilt with new signage, lights, security cameras, elevators, and wider platforms. Reconstruction began on May 16, 2021 and was completed on July 20, 2025. During Stage A, the two original northbound tracks were closed permanently, and the main entrance was closed with all northbound trains using what the original southbound Red line track and platform and all southbound trains using the original southbound
Purple Line Express track stopping at a temporary side platform. Purple Line Express trains continued to skip this station in both directions. This time, the temporary station was an island platform located on what would be the new northbound Red Line track, located between what became a completely new pocket track (which had no equivalent on the original structure) immediately to the north of the site of both the original and permanent new stations (which was being used by all southbound trains), and the permanent Purple Line Express northbound track (which was being used by all northbound trains). ==Services==
