Wilson is a station on the Chicago Transit Authority's Red Line, part of the Chicago 'l' metro system. It is located in the Uptown neighborhood at 4620 North Broadway in Chicago, Illinois (directional coordinates 4600 north, 1100 west). It is the closest station to Harry S Truman College. The station has a large central island platform serving the Red Line. There are also platforms on the outside tracks that once served Evanston Express trains (as well as local trains before a middle platform was created), but these are no longer used as Purple Line Express trains pass through the station without stopping. Despite not being in revenue use, the southbound auxiliary platform is kept in operational condition and sees occasional service during reroutes, charters, and other unusual operations. In 2009, 1.8 Million Passengers used this Station.
