When rides go up the lift they are being carried be a chain dog. What happens if the chain dog breaks? It’s happened to me working on a ride, I snapped clean in half. What happens if the chain breaks? We don’t want the train to go backwards because it will catastrophically collide with the train in the station, and injure people in both trains. So devices called Ani-rollbacks or ARB for short, were installed to make the lift a one way trip.
