Someone showed this to me just a little bit ago and it's really cool! I'm looking forward to the update so I can make some cool stuff with rails.
It got me thinking though: will there be a way to set the speed of rail movement? I hope so! This looks great for machinery, but for an elevator that would be far too slow to go very far. Since I want to create Metroid Prime-inspired elevators, it'd be a real bummer if I couldn't set the speed of my elevator's rails to something fast enough to at least get that kind of feel. Plus, I don't want to spend 30 seconds getting from one deck to another on my space ship.
Just a thought. Hopefully this has already been planned out.
