Project Management Oversight (PMO) Capital Projects

This project funds engineering design services for the replacement of the Stoney Creek Bridge on Metra’s SouthWest Service. The bridge, constructed in 1917, spans over Stoney Creek in Oak Lawn at milepost 16.3. Construction funds are provided in future years.

This project involves lifting a bridge between 78th Street and 79th Street on Metra’s Rock Island Line. The bridge spans over three sets of railroad tracks owned by The Belt Railway of Chicago and Norfolk Southern in Chicago at milepost 8.7. This project is a necessary component of the new Auburn Park station project.

Elevated Track and Structure Systemwide - Funding will be targeted at preventive maintenance projects for various Infrastructure units such as Track, Structure and Power. When certain maintenance tasks are needed to repair or replace asset components in order to maintain the working life of rail system, specific component campaign work is conducted. Capital maintenance work is targeted at the following areas: Elevated Track and Structure - repair/rehabilitate track and structure elements in order to eliminate slow zones and upgrade the right-of-way along the elevated structure throughout the rail system. Traction Power Substations - program that repairs and upgrades equipment at various traction power substations currently in service. Tactical upgrades correct deficiencies and avoid service reductions due to failure and overload of aging equipment. Third Rail and Heavy Traction Power Cables - Preventive maintenance work is performed where necessary to repair/replace heavy traction power cables that feed the third rail along the tracks currently in service at various locations throughout the rail system. Rail Signal Systems - Program provides for signal equipment repair along the rail right-of-way, signal equipment on rail cars, and the reconstruction of electronic components of the signal system, including relays and circuit boards. As necessary dedicated small renewals and system modifications are also completed. All work is planned/performed to maintain the asset(s) in proper working order through its quarter life cycle, while a more extensive rehabilitation is planned at the mid-life of the asset.

Engineering Design, construction, and related services for the replacement of Bridge 86 on the Rock Island (RI) Line will be funded by this project. Bridge 86 dates back to 1916 and spans 78th Street at milepost 8.62 in the Auburn Gresham neighborhood of Chicago. Contemporary construction methods will allow two-track service to be maintained during the bridge replacement. The replacement abutment wall at the south end of the bridge will include ground-floor space for a leasable storefront, a new staircase, and an elevator. The elevator and stairs will provide an accessible pathway from 79th Street to the new Auburn Park station boarding platforms and headhouse. This project is a necessary component of the new Auburn Park station project.

Subway Waterproofing & Track - Funding will provide for critical waterproofing patchwork needed to continue rail service through the Blue Line O'Hare branch.. Due to funding restrictions CTA cannot move forward with original scope of work to mitigate water infiltration in the Dearborn subway.

This project will provide for the reconstruction of bridges and retaining walls on the Union Pacific North Line, and Ravenswood Station.

The CTA's Forest Park Blue Line Upgrades Project is the first of four phases of the Forest Park Branch. This project will provide for new trackwork from Halsted to IMD, an accessible station at Racine, advanced utility work, and a new substation and traction power equipment upgrades at Hermitage. This work will enhance service quality via speed, reliability, and comfort, and improve operational efficiency on the Forest Park Branch of CTA's rapid transit Blue Line service.

Blue Line O'Hare Branch Traction Power Improvements GTT - Project will include targeted track repairs to remove existing slow zones on the Congress Branch of the Blue Line. CTA has identified traction power voltage drop issues along the Blue Line. Scope of work will include but not limited to the following elements: New infill substations, infill wayside energy storage systems, infill tie houses, third rail replacement, addition of auxiliary negative rail; work will be performed by an outside contractor. In addition project will aslo provide for the replacement of ties, track fasteners, footwalks, and incidental signal and traction power; this part of work will be performed by CTA Field Forces.

The Green Line Improvements project will largely focus on track replacement and structural repairs.This funding would support track improvements on both sides of the Lake Street Bridge, which isscheduled to be completely replaced by the Chicago Department of Transportation in 2023. The scopeof the project will include: improve the curve geometry on the east side of the bridge; replace thetimber ties and rail fasteners, install new gauge planking, replace equipment at both the east and westturnouts, and replace structural steel framing for the three side platforms adjacent to the track.
