When building and testing my Eurofighter, I accedentily forgot to tweak the brake stuff and my train shot through the 2nd station and almost crashed into the other train. Weirdly enough, it didn't crash but sticked to the other train. And when that one left the station, the 2nd part left also. They went trough the corner without a problem, but they crashed when the front piece touched the lifthill.

Sadly, they crashed:
I'll post a movie on YouTube later.
