>>9713954The railroads could be a problem, but I think that there are workarounds on the roads. I think you can compensate. There was a tutorial that I read once that did all the math of it. Maybe it could work?

As for the inclines, it would be trick to make it legal. Maybe there's a piece that could connect the rails?
