What's...with...the...pink?
Honestly, don't get it. I thought the colours of the track were ackward, but added with pink. Lame IMO.
But otherwise, it looks great! How many trains are there for Insane? In Kirnu (and probably Inferno) there are three, with stacking occurring always. In Kirnu it goes like this:
1. Train dispatches
2. The first of the remaining two "trains" enters loading area, whereas the second enters unloading area.
3. Before the now first train gets loaded (no pun), the dispatched train already makes it way through the track and enters "station level", but practically it's still in brakes, and cannot thus unload. So, the passengers have to wait.
I hope this stacking problem will be fixed.
