A launch track is always straight and is usually banked upwards slightly, so that a train would roll backwards to the station in the event of a loss of power.A launch track serves the same basic purpose as a lift hill - providing power to the train - but accomplishes it in an entirely different manner. A lift hill gives the train potential energy by raising it to the highest point in the track (and not significantly accelerating it). A launch track gives the train kinetic energy by accelerating it to the maximum designed speed (while not significantly raising it).A launch track normally includes some form of brakes. Depending on the type of coaster, these brakes may be used in every run of the coaster (this is normally found on a Shuttle roller coaster where the launch track also serves as the main brake run) or they may only come into play when a rollback occurs, normally on a complete-circuit coaster such as Top Thrill Dragster and Kingda Ka. In either case, the brakes are retracted to allow trains to launch, and are engaged at all other times."@en }
