Yeah, unfortunately the block system is very basic right now. Right now, signals switch themselves (and the signal before them) the moment a train drives over the signal. The "jump to station" feature just ignores this.

I want to completely refactor the signal system, but that's only going to happen in 0.10 unfortunately
