SouthWest Service trains will shift from Union Station to LaSalle Street Station with the reconfiguration of the 75th Street Corridor under the auspices of the Chicago Region Environmental and Transportation Efficiency Program (CREATE). This will happen no earlier than 2025 when construction is scheduled for completion. Additional mainline trackage will also be built between LaSalle St Station and 74th to handle the increase in traffic. LaSalle St Station will also be expanded. This would relieve congestion at Union Station and improve reliability for the SouthWest Service, as well as allowing more trains to run in each direction.
