Here is the bottom of the big hill. The rubber track at the bottom is controlled by a separate motor, since it is critical that the train mesh with the chain to the top at the right place. The carnie to the left is controlling the rubber track here. Most of the changes that would be needed on a future model would be made in this area. First, we need a couple sets of wheels (as used at the station), connected on the same motor as the belt, before the train reaches the belt. These would serve three purposes - they would automatically brake the train so it doesn't hit the belt to hard and get damaged or bounce off, they would push the train to the belt if it was going too slow, and they would push the train onto the belt in the event of any bounce. In actual use the train did not properly engage the belt about 50% of the time.
