Entering the Loop, Orange Line trains will make their first stop at Adams/Wabash, then Madison/Wabash, Randolph/Wabash, State/Lake, Clark/Lake, Washington/Wells, Quincy/Wells, LaSalle/Van Buren and Library, then proceed to Roosevelt and resume the normal route.
Crews will install new switching equipment as part of the Loop Signal project that will replace the signal and train control systems in the Loop. The Loop Signal replacement project is expected to conclude in late 2010. The project is being conducted in phases to help minimize the impact to customers. The majority of the work has taken place on weekends and in the early morning hours.
