While he agreed that Red Line expansion is a good idea, Vallas noted that given the $2.3 billion price tag it is “unlikely” that project will come about soon. He recommended improving east-west bus service and making the CTA faster and more reliable by increasing capacity, trying traffic signal priority programs and studying the idea of reinstalling skip-stop service on the Blue Line to O’Hare, and maybe the Red Line too. “Skip-stop” means skipping some stops along a route to increase speed and capacity; the CTA phased out the practice in 1995.
