Station, Track & Infrastructure Improvements

Big improvements are in store for the more than 80,000 daily riders of the CTA’s Blue Line O’Hare branch. Among the benefits of the multi-year, $492-million Your New Blue project are a variety of station, track and infrastructure improvements.

The project has begun track work and is currently focusing on station renovations. Find specific improvements headed for your area of the Blue Line here:


As we upgrade the Blue Line, we will do our best to limit inconveniences. Riders will see temporary station closures and small delays overnight and on weekends. Check out the latest information on systemwide service changes, sign up for CTA Updates or follow @CTA on Twitter to stay up-to-speed on work that might affect your trip.

Damen, Western & California stations

Completed January 2015

Station rehabilitation work began at the California station in fall 2014, followed by work at Western and Damen. Though the California and Damen stations were temporarily closed, they were not closed at the same time.

  • California was closed for 42 days, from Sept. 4 until Oct. 16, 2014.
  • Damen was closed for 63 days, from Oct. 20 until Dec. 22, 2014.
  • Western remained open throughout the improvements.

During the closures, additional #56 Milwaukee bus service was added during weekday rush hours, with “owl” service during overnight hours to link the closest stations in either direction of the closed station.

In addition, Divvy, a program of the Chicago Department of Transportation, is Chicago’s bike sharing system served as an alternative for customers during this period. There are Divvy docking stations located near the Damen and California train stations, their neighboring Blue Line stations and throughout the neighborhood. See a map of where Divvy stations are located or find more information about this CDOT program at

Some temporary street and alley closures were necessary, as well as parking restrictions, at various times during this project. In the months prior to work beginning and then throughout station work, CTA detailed this project information and impacts to service for Blue Line riders, as well as local elected officials, community members and business owners.

Track & infrastructure work

Milwaukee Elevated improvements

Major improvement work on the Milwaukee Blue Line tracks occurred in 2014, improving the elevated tracks near Milwaukee Ave., from south of the Logan Square stop through the Damen stop. This section of the line opened in 1895 and the structure that supports the tracks was also built during that era.

The project's scope for the Milwaukee Elevated includes:

  • Replacement of wooden track ties atop the structure
  • Replacement of tie plates and fasteners
  • Replacement of foot walks

More information: Milwaukee Blue Line Track Renewal


Dearborn Subway improvements

The Dearborn Subway was largely built in the late 1930s and early 1940s, and opened in 1951. Blue Line service operates through the Dearborn Subway from near Division to near Clinton, through the downtown area .

The project’s scope for the Dearborn Subway includes:

  • Installation of water management system in the subway tubes/tunnels
  • Replacement of damaged concrete rail ties
  • Repairs to station caused by water infiltration, including:
    • Repairing and repainting walls in tube/tunnel
    • Repairing, cleaning and refinishing platform surfaces
    • Installing new platform lighting
    • Replacing signage


Kimball Subway improvements

The Kimball Subway, inside which the Belmont and Logan Square stations are situated, opened in 1970 as part of an extension of the old elevated to Logan Square through a subway and expressway median line out to Jefferson Park (before the line was extended to O’Hare).

The project’s scope for the Kimball Subway includes:

  • Installation of a water management system within the tunnels
  • Replacement of damaged rail ties
  • Repairs to station caused by water infiltration, including:
    • Cleaning masonry walls in tunnels
    • Repairing, cleaning and refinishing platform surfaces 
    • Replacing signage at platform

Signal work

Starting in early May, crews will begin work on one of the biggest components of Your New Blue: The modernization of signals between Jefferson Park and O’Hare. The $200M project will help us improve service, increase reliability and add more trains to the line during the busiest parts of the day.

The project—the first such overhaul since the line was extended from Jefferson Park to O'Hare in the early 1980s—will help ensure less-crowded commutes, better service and fewer delays.

Improvements from the signal project

The work will replace signal relay houses and the equipment inside them, cabling and switch machines over the approximately eight miles of Blue Line (covering more than 16 miles of track) from Jefferson Park west-northwest to O'Hare.

Benefits include:

  • Changes to the design of the signal system that allow us to run more frequent service between Jefferson Park up through O'Hare (more frequent trains allows additional capacity)
  • Improvements to aging equipment, infrastructure and signal systems that date back to the early 80s, decreasing the likelihood for signal-related delays and improving overall safety and service reliability
  • Improvements to track infrastructure and switches in the area just northwest of Jefferson Park where we store/turn back extra trains (the middle track near Foster Ave) which supplement service and capacity in the busy core of the route to improve safety and reliability in the area
  • "Worker-ahead" signals and warning system improvements to help protect track workers and other personnel at track level such as for times when track maintenance work and inspections are being done

Some track replacement work will also occur in conjunction with the signal upgrade project in the O'Hare subway/tunnel approach.

This work is a critical part of our broader efforts to bring more reliable, better and more frequent service to the Blue Line and, along with other upgrades happening in tandem, shave time off people's trips and increase overall capacity.

Impact to service

What types of disruptions should I expect?

In addition to more common overnight and off-peak work requiring trains to share a single track, several temporary closures of portions of the Blue Line—typically between two stations and over a single weekend at a time—will need to occur.

Only one section of route will be closed at a time, and a major, load-and-go shuttle bus operation to bridge a closed section of the route will be provided, free to all riders upon boarding and with free reentry to the Blue Line with Ventra Card, Ventra Ticket, or contactless payment.

This impact will be similar  to work CTA completed on the Milwaukee Elevated section of the O'Hare Branch of the Blue Line through Logan Square, Bucktown and Wicker Park a few years ago. We encourage riders to allow significant extra travel time due to the need to change for shuttle buses when major work events are being done.

To find out when work might affect you, visit our Blue Line page to see all current, upcoming and accessibility alerts that affect Blue Line service and riders. We also encourage you to sign up for CTA Updates to get texts/e-mails about both planned and unplanned events that might affect your trip.

Why are these disruptions necessary?

This is a complete replacement of signaling systems from Jefferson Park to O'Hare and will require periods of major work where cabling and conduit work in the track bed will need to be laid, removed and/or replaced.

Work on rails - such as replacing switch equipment, signal equipment along the track, hardware and conduit along/under the track, electrical connections and rail joints - require that we stop train service to let workers proceed safely and quickly to get the job done.

Big picture benefits

These improvements are a key step to running more trains, more frequently, with even better safety and reliability, allowing us to add more service and capacity to accommodate the bustling Blue Line corridor from downtown to O'Hare in the future.

Adding capacity and being able to run more frequent trains not only provides a better commute, but also has the added benefit of decreasing the likelihood that a moderate delay will have rippling effects, such as slower recovery after a delay, more crowded trains and platforms, longer station stops and sluggish/uneven service across the whole line.

Together, along with power upgrades to allow us to have the track power capacity to run more trains, track improvements on multiple parts of the O'Hare branch and new railcars to replace aging ones, this major signal project plays a key role in providing you with a better Blue Line!
