I will add a section to my L-shaped H0 layout adding a 280cm x 60cm (112" x 24") with access to and exit from a passengers station.
As it is impossible to turn given the room constraint, the locomotive must move from the front to the rear. Now I will have to turn it 180 degrees using a turntable unless I get one of those (mostly GP's) that could be driven backwards pulling the cars, in this case using the bypass parallel to the main track.
I want it to be a D&RGW passengers service.
Here are attached 3 possible layouts, please tell me if they are sound or not, and I will appreciate any ideas or suggestions.
