My first trackplan. The grey and light blue Santa Fe mainline goes over the purple and maroon coloured Rock Island. At Union station the RI line is 5,5 cm lower then the SF line. They come to the same hight just past the grainelevator on the right side of Union Station. To the left and behind Union station lies Kansas City Missouri. The meatpacking plant and several smaller industires will be on the peninsula.
I'm getting close to what I think the layout should end up like, added the second room and made some alterations, its not as crowded as it looks for there are different levels in the second room.
