I still don't agree Gazza. If the wheels stopped before a car ran onto them (in order to "brake" the car), it would take tread off the tyre and when the car was ready to proceed the wheels wouldn't be directly under the car. It would also be hard to control where the car is stopping depending on the tread left on the tyre (which would change the rate of deceleration). If what you are saying is true then in order to bring the carriage to a stop, (eg. before the lift or at the loading station) it would be scrapping tread off the tyres. I am pretty sure the wheels would move the car forward until it reached some type of sensor which would stop the motors in the track at the right time. But... as always, I want someone else's opinion on this.

Rabid, do you know when the expected completion date of this coaster is supposed to be? Some people are saying September, some October and some say Christmas Holidays.

I am talking about the wheels "locking" up, not actual air brakes closing (e.g. wheels locking up at the station and before the lift etc.). I was pretty sure they waited until the car was directly over the wheels and then they stopped the tires at this point. This is what it looks like to me at the loading station. It would allow them to start the car again very easily. Richard? I'm sure you know more than anyone here, what do you think happens?

We can always make a full day out of Movie World as well...

I am not suggesting that an entire heat/smoke detection system doesn’t exist, in fact, he/she told me it does, and explained what happens when it detects a fire. Yea, as I said, Ill ask him/her again when I see them. Very true. You not only have to detect a fire but also know how to evacuate people and distinguish the fire as quickly as possible. Alex, you have made some good points about the onboard fire sensors being unnecessary. I mean, if there was a complete in house system, the onboard sensor would appear to be overkill. I have another question, this time it’s about the logic circuit that controls the “wheel brakes” in the track. If for example, a car doesn’t make it past the next zone successfully, the wheels in the track stop turning so the previous car will not continue into the next zone and collide. Do the wheels that connect the two zones stop turning as soon as the zone is occupied or does it wait for the car behind it to hit a sensor (e.g. just in front of the wheel) so it has less wear on the tires and the wheels will then be directly under the carriage allowing the car to start again easily (e.g. the car would hit the sensor when the wheels are directly under the car, stopping the wheels and the car simultaneously). Attached is a diagram of what I mean.

Thanks everyone for your response on the subject, to make it easiest to say what I have to say I will quote individual posts from each person below. I am not saying I fully believe this, if I did, then I wouldn’t have posted here looking for an answer would I? And to make it clear, this isn’t “Adam’s crazy theory,” it’s what I’ve been told. Onboard Car System 1. Motors and Brakes Personally, reading what others have written, I agree. There is no need for cars to have motors or brakes onboard the cars. This would not only be useless in the main warehouse building but also in the first part of the ride as brakes / motors are already installed in the track and are unlikely to fail, and if they did, they would fail safe. 2. Fire sensing technology This is something that I truly believe is installed in every car; a heat sensor that points directly ahead. The data from this sensor is fed to a radio transmitter that sends information directly the main computer. If fire / heat is detected in front of the car it would automatically signal the emergency evacuation alarm. I cannot see how my friend could be wrong about this, I mean, he/she wouldn’t make it up, yet I still have no proof whatsoever that this system exists but I am going to ask him/her again next time I see them (should be over the next two or three days). After what happened in Luna Park, this technology is a great idea, although there is no confirmation that Scooby Doo has this. Previous Posts Exactly, this is how I figured it would work before I asked him/her. This would allow for the quickest evacuation time and the harness could auto release at each station and light up the path to the exit. Well I thought because it was indoors and there was greater chance of a fire but I have been known to be wrong. This isn’t what I meant Gazza, and you knew it as well. Alex, if you actually read what I say: Richard, I simply want to know from someone who actually operates the ride or is 100% sure that this isn't true. Questions Richard (or anyone else that knows as much as this guy), are there many differences between the fire procedure and the e-stop procedure? Does anyone else have any reasons as to why fire sensors wouldn't be on the car? Has anyone been on the ride for an emergency evacuation? Thanks.

I got the information from someone who operates the Scooby Doo ride and has read the handbook (as is required to operate the ride). I am happy to discuss the subject with you (Richard), wonderbus, Gazza or joz, but I can't be bothered with Alex's stupid comments. The reason I said I didn't want to debate it was because I wanted someone else who actually operates the ride to answer the question but it seems that no one here is able to do so. Let’s begin the debate… For a start, this information was given to me by someone who operates Scooby Doo. This person would not lie to me and unless he/she was very confused (I am going to ask him/her again next time I see him/her) then I think the information he/she provided would have been correct. Maybe the individual carriages do not have motors or brakes, but why are they equipped with batteries and why have electrical contacts been added to the track? Surely if they were only running LED’s then a 9V battery would last the day. … I have to go out now but when I get back ill post a few more things. Also, thanks Richard for taking the time to help me out.

Richard, I simply want to know from someone who actually operates the ride or is 100% sure that this isn't true. As I said, I don't want a debate, I want an answer from an experienced user. So far, no one here actually works at Movie World but are all willing to get into a debate. Richard, are you 100% sure, with full proof, that the cars do not have motors and/or brakes? If you can answer this question than I will be happy.

Alex, seriously dude you need to find something else better to do with your time. I have removed the other thread and rephrased the question as this sort of information is some what confidential. Alex, you can think what you like. I don’t care. I am not here to debate whether this is true. You are just guessing based on other rides of this type. I want answers, not idiots telling me to shut up. Don't even bother replying to this thread Alex.

An update to this thread; Movie World have finally removed the "new" labels from both the Scooby Doo ride and The Matrix Exhibit on their website. Just thought I’d let you all know

I am also trying to extract more information from my source so I will let you know how I go.

Can anyone that works at Movie World confirm if the cars on Scooby Doo have brakes and/or motors in them?

I never even thought about that, I was looking at the Movie World site. Thanks.

Does anyone know which rides / attractions opened with the park (Movie World) in 1991? Thanks.

Sounds like a good idea. I don't think they are moving it to the Superman area, or are they?

I would have thought the later explanation would have been easier Nah I didn't ask while I was actually at Movie World. I have removed the posts above that related to how I think it works (as I don't want this info on the net), no one here seems to know anything for real and are just guessing based on other rides, so ill leave it at that. Thanks for the comments though (especially kenny).

This information came from someone who operates the Scooby Doo ride and has read the hand book (as is required to operate a ride). Gazza, I agree with you completely. The system you describe still exists, but if there is a MAIN SYSTEM FAILURE, thats when the secondary system jumps in. What kenny explained (and thanks for that too) would have been when the main system was online and fully operational. The reason for posting was to find out more information on how the cars operate but no one seems to know anything.

Yea, Universal do have some great rides. I think the laser room is pretty cool. I have never seen this in a ride before, I think it makes it better than going around a completely pitch-black room. Where abouts are the cracks of light coming from? The emergency exits?

I have never been on Revenge of the Mummy but I have read some reviews of people who are pretty well known in the coaster world, and they rate it higher than Disney.

It doesn't matter where I got this info. I am not here to debate it, I want someone to tell me how the two systems operate - but I'm not sure if anyone here actually knows. Exactly! I agree. This would have to be the safest as it allows for the quickest evacuation time. It does seem to complicate things but I think the idea for this is a "fail-safe emergency system" - two completely independant systems. Track system Just like a normal roller coaster. Car system The cars contain radio equipment and onboard motors which are driven by electrical contacts on the track and a built-in battery (as not all parts of the track have electrical contacts). The “eyes” on the front of the cars are heat / distance sensors – a very good idea in terms of safety (put the sensors where the people actually are) – and this information is radioed back to a central control computer. If an object obstructs the track, then the “eyes” will activate the onboard emergency brakes – in the car – and radio to the control system to shutdown the ride. In the event of a fire, when a car senses heat, it radios this information back to the central computer and if it’s before the lift, then the cars behind it are reversed back to the station / nearest exit for immediate evacuation. In the event of a fire power is not killed to the entire building nor the central computer; it continues to operate but the ride is ordered to stop. But, I am not saying this is correct, what I really want is for someone to tell me if it’s correct, someone who actually knows. Feel free to PM me.

Thanks Alex for your post but I was looking for someone who is familiar with the operational procedure of Scooby Doo. But as for your last question, Scooby Doo employs a fail-safe double system. There are two independent systems: 1) The track system (which includes wheels and brakes on the track) 2) The car system (which includes brakes and a motor in the car) I don’t mean the ride continues as per normal. The whole ride would go into “emergency evacuation,” with flood lights, PDA systems, emergency services alerted etc. but if the car stopped in an area that was about to be engulfed in flames, the car has an infrared sensor so it can reverse away from the situation. The default option would be for the car to stop. As far as I know; the cars are designed to communicate with each other and they are programmed to move into a “safe area” for evacuation, for example, you wouldn’t want to evacuate where there is fire. The reason for posting this was to find out more about these two systems. I am not 100% sure on the operation procedures of these two systems but if anyone can help me out who either works for Movie World or has worked with indoor roller coaster emergency systems. Thanks. Rabid, if you could tell me if any of this is true or not that would be greatly appreciated.

Thanks screammachine and Skipper. Is the backwards drop on Mummy very big? Does it accelerate fast away from the station or relatively slow? Thanks.

I think the height is 40m, and the top hat isn't inverted. More info on the ride is here - http://www.rcdb.com/m/id2999.htm.

While the emergency stop button kills the master system, the secondary “car system” continues to operate. This is controlled with an individual computing system in each car driven by a battery. There is also an infrared sensor at the front of each car which is fed directly to the onboard computer. Extreme heat / fire in front of the car will cause the onboard computer to reverse the car (and signal the cars behind it) away from the danger – or return to the station – depending on where the car is. Does anyone know anymore about the two systems on Scooby Doo? I know that anyone who works at Movie World will be able to help me out. Thanks.

Thanks for your answer wonderbus, much appreciated. What about in a Fire? The cars have infared sensors in them and if they don't sense fire in front of them wouldn't it be easier to proceed to the brake station so they can get everyone off the ride as quickly as possible, or is this what they do? Also, if the cars sense fire infront of them, they start to reverse, what happens if they do this after the reverse drop? They surely wouldn't be able to make it up that drop.
