A rollback is when a launched roller coaster gets launched up the track and falls down before the train makes it to the top of the main hill. This happens on Top Thrill Dragster and Kingda Ka many times.
Very rarely, trains may rollback on the lift hill if the anti-rollback device fails. This can cause a collision with a train in the station.
