When we are only using one side, it is because one of two reasons. Either the Park admins have told us to, or 2, because of crew shortage, we do the best we can over there, trust me i know, as a 3rd year working the ride, it isnt easy but we move as quick as we can to make run smoothly. Plus think about it, by the time the first train has dispatched, the second has to roll in, sit up and the people get off of it and then we reload it, it takes about 2-3 minutes for all that to occur, and the ride is only 2min and 35 secs long
