[2] The program monitors the full route of the Red Line, which does not include the stations of Loyola, Bryn Mawr, Sheridan, or Wilson.
In May 2012, the CTA started to work on the North Side Main Line stations which includes Jarvis, Morse, Granville, Thorndale, Berwyn, Argyle, and Lawrence.
The project also included the elimination of slow zones in which trains were forced to travel at reduced speeds due to sub-optimal track conditions.
[10] Track conditions were causing Red Line riders to experience longer travel times, crowded trains and unreliable service.
The tracks had extensive repairs which were able to be completed over a five-month period with full closure, as opposed to a four year schedule if construction was limited to weekends only.
A free shuttle bus system was implemented from Garfield to the Dan Ryan stations south of 63rd Street and from Roosevelt to Cermak-Chinatown.
The two bus routes would travel south from the 95th/Dan Ryan terminal either down Halsted Street or Michigan Avenue, while the heavy rail routes left for consideration were the Halsted and Michigan corridors (either underground or elevated) as well as the Union Pacific Railroad corridor (elevated or trench), which would traverse southeastward toward the South Shore Line.
[17] In December 2022, City Council approved the creation of a district that will send nearly $1 billion in tax revenue over the next few decades to extend the Red Line south of 95th Street, a major step toward completing the project after a half-century of false starts.
