The basics: 22 x 19 foot room, 30" min. radius, DCC, room for two through trains (Port Huron Pontiac each way), a local to the elevators, etc. and any traffic to the busy tractor plant in Romeo.

A staging yard would be located under Romeo with enough room for staged trains. Additional staging yards / storage could be added under other sections. This is a quick and very basic plan. Lots of orchards and farm land for scenery. Rochester Jct. and other areas are modeled closely after track plans I have received or viewed over the years, though scaled and adjusted to fit. What's next, the Bay City Branch???
