Ends up taking up a lot of space. This is narrow gauge, so the trains can whip around tight corners (but it can't be anything more than 4 wheels).
It wasn't *too* expensive - I think N gauge would have cost more. The track isn't that much, the mdf/insulation foam I used wasn't loads - the trees etc. probably cost the most. I had the 3d printer already which cut obvious corners and the donor train chassis were 2nd hand on Ebay.
