Chicago & North Western Downtown Maps
I based the track plan off of these Sanborn Maps from 1942. I have included them below so you can get an idea. I did my best to crop and size them and then overlaid the module plans on them. There is a bit of modelers license here to get the track to fit four foot modules, but the layout closely matches the number and alignment of tracks. I added a switch or two to enhance operations when only some of the modules are in use.
