Northbound Chicago North Shore & Milwaukee Railroad train at 8th Street on the Chicago elevated tracks on June 9, 1946. The 17th floor of the YMCA hotel provided the vantage for this photograph. The high-speed interurban "North Shore Line" railroad connected Chicago and Milwaukee. At the time of the photo, there were two routes: the express trains used the faster Skokie Valley route while the slower locals ran on the Shore Line through the North Shore communities. North Shore trains operated on the elevated tracks in downtown Chicago, shown here, as well as the city streets of Milwaukee. The operation lasted until 1963.
