Just finished designing my railroad with RR track. The track system is MTH ScaleTrax. The room size is 14' X 19' with a 6' X 3 1/2' extension for the engine servicing facility. The layout is modular and extends against the walls of the room. It is 40 inches tall. The control system will be DCS. Turnouts are operated by Tortoise under the table motors. All cars and locos will have Kadee couplers. The Railroad will incorporate prototypical operating sessions.
The petroleum facility shows MTH structures, but I will be constructing my own facility using Plastruct. The rest of the buildings will be Korber, Walthers and the MTH brewery. Of course there can always be changes. Any constructive criticism is welcomed.
