Slow Zone Prevention & Signal Work on Loop Elevated Continues

November 11, 2008

Brown, Green, Orange and Pink Line Trains
Rerouted Through Loop

The CTA is performing slow zone prevention work this week on the Loop elevated tracks. Crews are replacing track and rail ties, and installing a new signal and train control system at the Loop junction of Van Buren/Wabash (Tower 12) and Lake/Wells (Tower 18). The new systems will help to improve the reliability of service by regulating train movement, speed and intervals.

The most intense work is scheduled on the Lake Street and Wabash Avenue tracks resulting in reroutes for Brown, Orange, Pink and Green Line trains. The work for this phase of the project on the elevated lines is scheduled to continue through Thanksgiving 2008.

Northbound Green Line trains and Brown Line trains will be rerouted in the Loop on Tuesday, November 11 from 10 p.m. until 4 a.m. the following morning and again on Wednesday night from 10 p.m. until 4 a.m. the following morning.

Brown Line trains will be rerouted from the outer track to the inner Loop track, and travel clockwise. Entering the Loop, Brown Line trains will make their first stop at Clark/Lake, then State/Lake, Randolph/Wabash, Madison/Wabash, Adams/Wabash, Library, LaSalle/Van Buren, Quincy/Wells and Washington/Wells, then proceed to the Merchandise Mart and resume the normal route.
