We are working to make the layout as accessible as possible, to provide a significant main line length, to create prototypical operational scenarios, and to allow for evocative scenes along the line.
The middle level functions as Illinois from Chicago to Dubuque-- a double-track main with a Grand Central Station, a bit of Rapid Transit, a quarry and many other industries . The lower level serves as yards for staging and set-up as well as providing a run-around track. The uppermost level represents the Iowa division operating a single track main. The levels are tied together with a double helix at both ends of each level.
