Generally with Scooby if it stacks up to the hairpins it tends to fault. Most of the time the ride can be reset, but occasionally it can't be reset causing an evacuation. Movie World has 2 voiceovers for each major attraction (Superman, Scooby, Justice League, Green Lantern and Wild West). You have a female one which is generally played first which alerts staff to prepare for a potential evacuation and the lights come on. "Ladies and Gentlemen, It is necessary to stop the ride temporarily, please remain seated and the ride will continue shortly." This also signals to the entry host to stop allowing people to enter the line in case of an evacuation. After a pre-determined amount of time most of the rides will go into an e-stop if they fault can't be rectified. Or in scooby's case, one fault might be fixed and then another fault will happen causing a "cascade stop" This is then followed by a Male voiceover instructing riders what is happening. "May I have your attention please, it is necessary to stop the ride. An attendant will be on hand shortly to assist you from the ride. When exiting the ride, please leave via the exit doors marked by exit lights, follow the directional lines to the marshalling area situated at the front entrance of the ride. Once again, someone will be on hand shortly to assist you. Thank you" And this keeps repeating. Still kinda sad that nearly 3 years later and I still remember everything like clockwork. Could probably even go back there and remember how to operate everything haha. A fun fact though, the most common locations for a fault to occur on Scooby is the Lift, Turntable and the block section around the corner from the unload station. Also, in regards to what Flea is asking, Scooby is ran fully automatic from the control panel. The control relief supervisor actually has no role during normal operation apart from observing the cameras and the load station. The ride is physically operated by the attendants at the load platform and unload platform and there are 5 e-stops on the ride (Load, Unload, Lift, High Zone and MOCC) When the ride faults the ride kicks into semi manual mode which is when the supervisor comes into play, where he can attempt to reset certain faults. However if it's a lift or turntable fault the ride will be e-stopped as cars can not be moved on the turntable or lift with passengers in it. Also I think it's 90 seconds with any cars stopped in high zone that the ride goes into e-stop if i'm not mistaken. Most rides at Movie World have minimal actual operation by the supervisors except for initial startup. Wild West for example if all goes well the supervisor will only have to hit the station stop button throughout the day and the e-stop at the end of the night.
