When it came to the trolley animation I encountered a problem, the trolley changes angles at the bump, this causes spleening problems as it would appear that the trolley would hold this angled pose for the entire animation, it gave the comical impression that it was reving along. When I was unable to solve this, I manually made each frame, this is why its not as smooth as I would have liked as, if the spleening was successful, I could have had more frames.
