Chicago Transit Authority (CTA) Ravenswood Connector Rehabilitation Project

Chicago Transit Authority (CTA) Ravenswood Connector Rehabilitation Project Overview

Chicago, IL

GAI’s Train Controls Group is incorporating new signal control microprocessors for the Ravenswood Connector line—the elevated part of the “L” between Armitage and the Loop, currently used by the Brown and Purple Lines. These microprocessors will interface into the existing relay logic control at the adjacent CTA location. This design will help increase the number of trains able to traverse the track, reducing delays during rush hour commutes. This design also provides room for expansion and upgrades of the signaling capabilities of the project locations in the future.
