Here is my trackplan:

It incorporates a double track loop on the lower level and also a branch line which runs from the mainline station on the lower level up to a country station/goods shed on the upper level. The lower level will be themed as a town and the upper level will be countryside.
Here's a few construction pics I have just taken: -
You can see both the upper and lower sections and the incline constructed using ideas found on here. I have cut and laid cork floor tiles as a trackbed and painted them grey which will then be ballasted.
Any comments or suggestions much appreciated.
Paul.
