This is the view of the back of the train. Take a careful look at how the wheels are constructed on Scenic Railway. Each metal wheel is flanged to make contact with the inside of the rails. There are no wheels on the side of the rails. Most importantly, there aren't any up-stop wheels located under the track!
The two metal objects under the middle of the car are the pads for the brakes. These particular pads are fixed, but will interact with brake pads scattered throughout the coaster's course. The brakeman will control moveable pads under the middle of the train.
