Hi Tom, thanks!
Yeah, I'm planning an automated level crossing and (Hopefully) some traffic signals at the junctions. But I think motorising the Haunted House is my first priority. I had it connected but the motor spins just too fast and the drop tower doesn't have the effect I'd like.
As regards the terrain, I'm a novice, so a lot of tiles for footpaths etc with some trees / shrubs dotted about but I need to build a cliff wall from the bottom level to the upper level and that's going to take some time.
