So what to build in a layout that is small and in a box, that will look as realistic as I could possibly make it.

The running line would be a loop
There would be a passing place
A station
A pond
A station yard
A small goods yard?
A house
A garden with a potting shed
A road bridge
A bridge over a stream
A small scrub land field
A road
Running line on an embankment
Lights
Trees and other vegetation

Quite a list but I reckoned that I could fit it all in.

I drew up on some tracing (baking paper) my design for the layout and also the design for the baseboard layers.

I also discovered setrack 009 points that were much smaller than my streamline ones and this would aid the track layout.
