I like your concept. I offer some suggestions, FWIW
- Perhaps you can keep the end doors for ability to move large pieces of wood, etc, into the train space.
- Railroad height. Model railroads always look better when they are higher.
- For the occasional child, a movable step, with a low rail. Since you don’t appear to have any operating accessories, a child’s interest will quickly wane. Experience
- If you raise the elevation, you can tuck a lower level staging yard into the plan, located near the front of the yard area, with, hopefully, a reasonable grade to reach a merge with the main trackage. The present staging track location almost guarantees it will seldom be used.
- That given, the area along the back wall could be used for a station façade and a city façade (like John Armstrong’s model RR). I assume passenger service.
- If you raise the elevation access to the accesses will be a bit less painful.
- Depending how you arrange the toilet, you could run the track through a corner of the bathroom and hide the fact with a mountain.
- There are several industry tracks with no obvious space for industries.
- Depending on the grade required, you could raise the engine service area above the end curves with a suitable tunnel and provide more room.
- I assume from the turntable that you will be running steam. Must you have a turntable? If your layout represents a division point you can do without and leave considerably more room for engine servicing facilities. Including the inevitable diseasels…
