The mock up in HO scale is three feet. in G scale (1/24) the outer plywood circle is four feet .Somewhere between the two will be the final diameter.The G scale cars on the40" table looks about right to me.
I have added the shack to the HO mock-up. In G scale it will be lower than shown here as the car will not be on its wheels.
The logging car represents the yet to be built locomotive with tender and the box car will be Morton's private luxury car,also yet to be built. If somewhere down the line I decide to add more of the sound stage, modules could be added around the perimeter.
The last pic is a mod I have made to the station by cutting out a portion of the cars wall ,pushing it outward to create a door, and adding a ticket wicket as in the film.The shack will be built over this portion of the car for now and changed later if required.
The passenger car has been completely gutted to get it ready for its new(old) interior.I think that I will start with the cars curved ceiling in plywood for now,later I can add individual boards if I want. I am assuming here that the passenger car was not cut completely in two and the ceiling of the car extended the full length of the shack as well.
There are over head drapes that roll down to presumably cut down on dust entering the passenger car half in a wind storm( in real life.)The shack was required to provide air and shade from the desert sun,rain of course would only be an occasional problem.The whole thing is heavily covered in dust,should be loads of fun weathering this.All that rough cut lumber will be quite a challenge to simulate in scale as well.
