You exit out a door opposite of where you'd originally get on the ramp. Then you have the long walk (but sort of fun to see the backside of SpM) to the front. Though you do have to cross the train tracks, there are CMs there to guide you/ help you and in 3 rides, we never were stopped to wait for a train, which would have been fun even if we were. There's really not a problem. It just takes longer (1 minute).
