The Chicago, North Shore and Milwaukee was an electric interurban railroad connecting its namesake cities with a line along the west shore of Lake Michigan. The “North Shore” name contrasted with the Chicago, South Shore and South Bend, as both were once part of Samuel Insull‘s electric empire. To relieve congestion in the crowded Chicago suburbs along the lake shore, it built a second line a couple of miles inland known as the Skokie Valley route. The railroad also had a branch to Libertyville Illinois.

In 1949, when this timetable was published, the North Shore operated dozens of trains a day. The shore line route had as many as 35 trains a day each way, while the Skokie Valley Route had around 20. The Libertyville branch had more than a dozen. This intensity of service led rail historian William Middleton to call the North Shore a “super interurban.”
