The North Shore Line - David Sadowski - Bog

"As late as 1963, it was possible to board high-speed electric trains on Chicago's famous Loop "L" that ran 90 miles north to Milwaukee. This was the Chicago North Shore & Milwaukee Railroad, commonly known as the North Shore Line. It rose from humble origins in the 1890s as a local streetcar line in Waukegan to eventually become America's fastest interurban under the visionary management of Midwest utilities tycoon Samuel Insull. The North Shore Line, under Insull, became a worthy competitor to the established steam railroads."--
