Can you mix purple and yellow and get red?

Can you mix purple and yellow and get red? Maybe you should. Is it time to examine the CTA rapid transit lines at the far north end of the system? For an eternity, the purple line has been a logical extension of the red, a set up that has created an unnecessary switching of trains at Howard Street on what could be viewed as a single set of tracks. Could the purple line be eleminated (or reserved only for its express service) and be incorporated into the red? The downside (if any) would mean relatively larger numbers of empty seats using the multi-carred red line as it moves northward through Evanston and into Wilmette. But the expense of such emptiness would be more than off-set by the savings and convenience of eliminating separte lines where not warranted. The third line to converge at Howard is the yellow. The name Â"Skokie SwiftÂ" has been relegated to history. It is hardly even appropriate at a time when a new station is being added on Oakton Street to serve downtown Skokie and, I believe, one considered for Crawford. Presently the yellow line cuts through Evanston without a stop, but the city of Evanston wants to see that changed. It has proposed that CTA add stations (where they once existed on the old North Shore line) at places like Dodge, Asbury, and Ridge...stations that would serve the southern fringes of Evanston and the northern most parts of Rogers Park, as well. Why not have the CTA go back to the drawing boards on this one. All they have to do is think of the former configuration of the blue line (OÂ'Hare-Congress, OÂ'Hare-Douglas) to create a more efficent movement of people on the far north side and near north suburbs. The plan would be thus: eliminate both purple and yellow lines (while retaining the purple Â"Evanston ExpressÂ") combine them into an extended red line service with Dempster (eventually replaced by Old Orchard)-95/Ryan and Linden-95/Ryan branches.>
