The idea of Metra running its Hyde Park and South Chicago-bound Electric District line more like a CTA 'L' line may be gaining traction. If so, much of the credit goes to advocate Mike Payne, who has been tirelessly promoting the concept online and at public meetings. He calls this proposed rapid transit service as "The Gray Line," since that's one of the few colors that doesn't yet appear on the Chicago Transit Authority train map.
