I
had been using a 2' by 4' portable resin table for a workbench and
it occurred to me that it might make a good base for a mini
layout.

I
decided on several criteria:
-
It
would be dual gauge
-
Each
gauge would have a continuous run
-
There
would be a dual gauge interchange, turntable and engine facility
-
Cassette
feeds for each gauge would connect to "elsewhere" and
would allow for introduction and removal of equipment
Next,
I wanted to expand my line drawing to get some idea of how the
layout would work by scanning the
drawing into PhotoShop and added scenery
and buildings. I thought Google SketchUp could be used to
"lift" elevated portions of the layout to give me a 3D
visualization. Finally, to smooth out transitions and complete my
drawing, I used PhotoShop once again.
Here is
the result:
