A recent Tribune article stated that it was torn up in the 80s, which seems a bit late (although not if it was out of service for 20+ years).
After crossing the north branch of the Chicago River, the third track (or more accurately, Kenosha sub track 1) began at what was once an interlocking at CP Deering, controlled by nearby CY Tower. It ran through Chicago's north side and through Evanston, terminating at Wilmette Tower, just south of the depot in that suburb, where the three mains shrunk to two. It's my understanding that Wilmette Tower was closed sometime in the 50's, and the track removed to a point in Evanston where the Kenosha sub connected to the old Weber branch, which provided a connection to the Harvard sub at Mayfair. As was the case on its other two lines, CNW used the center track bi-directionally on the Kensoha sub for both its rush hour commuter expresses and for routing long-distance trains around slower commuter locals when the need arose.
I don't know exactly when the track was removed, but I do recall seeing some CNW Evanston photos from the early 70's that still showed this track, but it was likely deactivated by that time, due to the closure of most of the inner-city stations, plus two Evanston stations at Calvary and Dempster. Eventually, the center track became the new track 1, and today, the passenger platforms on the west (outbound) side at Ravenswood, Rogers Park, plus the three Evanston stations were extended over to occupy the space of old track 1. They had been originally built as island platforms before the changes...
