Kingda Ka's over-the-shoulder restraint system consists of a thick, rigid lap bar and two thinner, flexible over-the-shoulder restraints. Because the over-the-shoulder portions of the restraint are not rigid, the hand grips are mounted to the lap bar. Kingda Ka's restraints are also held down by a belt, in case the main locking system fails. To speed loading, riders are asked to secure their own restraints if possible. These are checked by the attendant before launch. Kingda Ka's station has two parallel tracks, with switch tracks at the entrance and exit. Each of the station's tracks is designed to accommodate two trains, so each of the four trains can be operated from its own station.
