 The service, which was originally set up as a temporary service to be run for a trial period of 180 days (6 months), doubles service on both the Douglas branch and the Forest Park branch of the Blue Line.This is accomplished by routing all but 12 trains per day coming from to and adding entirely new service from the 54th/Cermak terminal in Cicero to The Loop via the Paulina Connector and the Lake Street branch of the Green Line.Pink Line trains operate clockwise on the Inner Loop track via Lake-Wabash-Van Buren-Wells before returning to 54th/Cermak.
