About the Forest Park Branch Rebuild
Much of the infrastructure along the Forest Park Branch of the Blue Line is original, dating back to 1958, when Dwight D. Eisenhower was President. While we have performed routine maintenance and made modest improvements over the last six decades, the infrastructure is far beyond its useful life and needs replacement or significant upgrades to address issues impacting day-to-day service, including:
- Only
4 of the 11 rail stations along the branch are vertically accessible to people who use mobility devices.
UPDATE: Now 5 stations are vertically accessible following the opening of the Racine main entrance.
- Overall speed and reliability of service has declined, with 72 percent of the branch categorized as restricted “slow zones,” requiring trains to operate at drastically reduced speeds for safety.
Under the Forest Park Branch Rebuild, we will rebuild a total of seven (7) rail stations to make them meet modern accessibility guidelines; replace the entire trackbed and drainage system along the branch; and upgrade the traction power system to support the electrical needs of modern railcars to meet current and future ridership demands.
We continue to work on securing funding needed to rebuild the entire Forest Park Branch. As funding becomes available, details regarding future phases of the Forest Park Branch Rebuild will be announced.

In 2023, the main entrance of Racine was demolished as part of the Forest Park Branch Rebuild Phase 1 work to address critically needed track and station improvements on the city’s west side. The rebuilt entrance was opened on October 10, 2025. The design includes an elevator and a longer platform.
This work is part of the CTA’s All Stations Accessibility Program (ASAP) and complements Mayor Johnson’s vision to make Chicago the most accessible city in the world. CTA’s ASAP Strategic Plan was released in 2018 and serves as a blueprint for making all rail stations fully accessible by 2038, plus upgrading or replacing existing system elevators. With the reopening of this station, 109 of CTA’s 146 rail stations (more than 70%) are ADA accessible.
The new station prominently features work by Chicago artist Judy Ledgerwood, best known for her signature motif of the quatrefoil, a four-petal flower shape organized within triangles and chevrons and painted in bold color combinations.
With the opening of the main station entrance, the Loomis auxiliary entrance is closing for reconstruction.
Upgraded power system
Crews are continuing work to upgrade the traction power system that provides electricity to the system and will result in improved service reliability for the Blue Line. This work entails the construction of a new substation over the right-of-way at Morgan Street, as well as other upgrades being made to power system components in the area (e.g., switchgear, transformers and rectifiers at the Hermitage Substation).
Phase 1 line cut is complete
As of October 8, 2023, Blue Line trains are running between the O’Hare and Forest Park stations, making all stops. Almost three miles of track, between the LaSalle and Illinois Medical District (IMD) stations, were rebuilt in 11 weeks.
Completed
Blue Line service will run in two sections:
- Between O’Hare and LaSalle (with main bus shuttle transfer at Jackson*) and
- Between Forest Park and Illinois Medical District, only.
Train service will not run between LaSalle and Illinois Medical District, however free shuttle buses will be provided to for connections travel through the area.
*Two shuttles will run between the Illinois Medical District and Jackson to provide accessible transfers for people riding through the entire work area (even though trains will run as far as LaSalle to continue to serve riders who live in the area and to maintain easy connection to Metra Rock Island District services at the nearby LaSalle Street Station):
- A local shuttle (route
) will run with intermediate stops at all times (24/7), and
- A peak-direction-only, express shuttle (route
) will also run—nonstop from IMD inbound to Jackson during the morning rush and nonstop from Jackson to IMD during the evening rush on regular weekdays, only.
Tips
- Forest Park-bound riders from the O’Hare branch should exit at Jackson for an accessible transfer and the easiest and most direct connection to the shuttle bus services.
- We encourage Forest Park branch riders to consider alternate routes to/from destinations, such as using local buses to the Green or Pink lines, which serve the Loop area and connect directly with Blue Line trains to O'Hare from downtown, which might allow you to avoid the shuttle bus entirely and provide a better trip.

(see also: Customer Alert)
Blue Line service will run in two sections:
- Between O’Hare and UIC-Halsted and
- Between Forest Park and Illinois Medical District
Blue Line service will not run between UIC-Halsted and Illinois Medical District in this shorter work area, and only the Racine station will be fully closed.
A local shuttle bus (route ) will run between the accessible Illinois Medical District and UIC-Halsted stations.
