We've hinted at the track for months, but it's finally ready to reveal. As far as I'm aware, it's the only genuine hill climb track out there. Cars race from the base of the mountain to the top and back down.
It's still a temporary track, and has to be setup and pulled down each time - which is a pain - but I don't have the space for another permanent track currently. It's also why the background of the diorama isn't as fullsome as the main canyon track, but I love how it turned out.
