Starting off with a single level frame. Adding the track and even dreaming of a nice complex bridge.
But this already provides the first challenge: how do you make a proper ramp?
Browsing the internet, I soon came to the conclusion that polystyrene was the way to go.
Wish some would have told me the two main issues with this stuff: cutting can not be done with a regular knife (bread knife worked best) and it leaves a mess. A serious mess.

Together with having absolutely no clue how to build nice green sides to the ramp, i decided on a different layout that did not include a ramp.

But now my layout is complete and the landscaping can commence.....
