Individual modules can be placed to the front and rear of main viewing areas. Adding more depth.
Extra modules can be added at any time. All or part of the overall concept can be shown at any one time.
This whole project will be nothing more than a series of highly detailed dioramas, connected with a railway.
I consider track, locos and rolling stock just detail parts that make up the concept.
I have absolutely no interest in prototypical train operation.
Just turn the power on and let the steam locos run.
PS. The above project was developed in 2003 and since been discarded.
