Hi Staalis, yes, and that was me. Here's the
link again. Why stop at two levels on a pizza display when you can have three? (I plan to re-film the layout now that it has been more or less finished, you can spot gaps in the video. Will post when I've done it.)
The main reason for it is simply space. I like to run as many trains as possible at the same time, and on this can run 4: 2 x 12v on the bottom, passing in front of the station, 1 x 12v on the middle level (these two are connected by a ramp, rarely used) and 1 x 9v on top. As well as the 2 at the bottom which can either run in the same or opposite directions, trains inevitably pass over each other, so there is always something happening at the front of the layout.
From above the layout looks like this
and the three levels on their own are fairly simple:
I've only used blue track in the diagrams to clarify which level is which!
The drawback with this layout is that with two hills for tunnels and support, a large viaduct at the back and a very dominant station (minifigs can walk to every platform!), there isn't room for many buildings. Ironically for this thread title, the only building in it at the moment is based on the Pizza Parlour,

PS - It is all Lego, there are no wooden supports for the mountains.
