Rocky Mountain Rails is a looping figure 8 layout using USA / Canadian Locos and rolling stock. Including bridges, tunnels and mountains, I have tried to include as much as possible on the original 4ft x 2ft baseboard (130 cm x 70 cm)
Under the layout is a single loop subway system with automatic running, signals and stopping processes.
Here are a few videos where the layout has featured:
