The “North Shore Line” was one of the most famous interurban lines in the America.  Known as “America’s Fastest Interurban,” electric trains of 2 to 6 cars such as 709 regularly reached speeds of 80+ mph along the high speed Skokie Valley route.  Service in the two namesakes was a little bit slower, with North Shore trains rolling down city streets in Milwaukee, and jockeying with “el” trains around the famous Chicago Loop.  The North Shore Line survived until very late in the interurban era (1963), and 709 was among the last to operate on the final day of service.
