I am stuck in a bit of a dilemma and hope that RMWeb is able to help.
A bit of background to start, I have bought and built a fantastic 1ft by 3ft scenic baseboard kit from Tim Horn for use on my next layout. I bought this after seeing "The sidings" and seeing the quality of layout that can be built from these boards.
My plan, as was suggested on another thread, is to recreate a 4 road depot, modeling the inside of the building, the exit to the fiddle yard being the exit of the layout to the fiddle yard. These will include inspection pits and the usual stuff you get in a depot. The basis being that the layout will be three walls and a roof, and only a view of the inside of the depot, the scenic opening being the 'removed' wall.
My issue I have is the 'opening' in the board to the scenic section is 25cm tall. Modeling OO gauge makes it a very tall roof for a depot. I had considered this to look unrealistic if it was modeled at that height? I had wondered about a blanking section above the roof, modeling the outside of the roof or just accepting that as the height of the depot.
Apologies if that is confusing! I've tried my best to explain it as much as I can!
