Roller Coaster Block Sections: Explained

[@pwhnckexstflajizdryvombqug9042]

Manual block system from 1963? Railway block systems have been in use since the 1800s... I imagine you mean 1863

[@coasterbot]

I did! I'm a roller coaster channel and there aren't many roller coasters built in the 1800s, so it's force of habit to say 19 something, sorry!

[@pwhnckexstflajizdryvombqug9042]

COASTER BOT: Thanks for the love! The context of the rest of the video makes it obvious that you intended to say 1863 😂😂. As much as it might not count as a roller COASTER because it would require each train to have breaks and their own power, it would be interesting to see how many trains you could run if you applied modern railway signalling systems to roller coasters, where the ride functions normally and would only use the brakes and motors if it gets too close to the one in front. If you have enough split platforms you could probably get a train every 10 seconds.

[@knexbox360]

Hi, Senior mechanical engineering student here, and I have experiencing interning with a roller coaster design company - you did an exceptional job with this video and explained everything perfectly! Well done

[@zacg_]

Another benefit of block sections (mid course brakes) is that for highly themed coasters it allows the train to stop or slow for a section of dark ride elements. I have no problem with a coaster being stopped and losing its momentum if there is a pay off in terms of theming.

[@coasterbot]

Very true!

[@ShaunPuzon]

@Blue Morpho Busy day or not, I would expect any ride operator trusted with the lives of several people at once to follow proper procedure and check the ride path before they override a crucial safety feature. The ride system functioned exactly as it was supposed to. An idiotic and under-trained employee trying to save some time was what caused the accident.

This is the safety system that prevents rollercoaster trains from colliding with one another. Let’s look at the block sections on...” -El Toro Ryan

[@themagicboy6548]

Hey the block brakes worked perfectly and stopped the trains. The collision happened because the operators overrode the stop.

[@boom_headshot]

@@themagicboy6548 True, but the computer shouldn't have allowed an operator to make such an override and I believe this has now been fixed on Smiler.

Wow, i’ve been into coasters for a long time but even i didn’t know there was such a thing a smart lifthills.

[@ryan_n05]

You know how Fury speeds up as soon as the train is completely engaged with the lift hill, and how it slows down at the top? That's a smart lift at work!

[@Meatloaf8]

TheSpanish Potato, ive always wondered why it does that... So now i will know next time i ride Fury 325

[@UP87]

TheSpanish Potato It might have other reasons, as well. The speed of the lifthill is added to the coaster when it disengages and starts to move by gravity. Thus the lifthill might have to slow down at the end.

[@Soonjai]

@@UP87 Some rides, lime Dynamite at Plohn, have a "Boost" feature on the Lift, giving it basically a slight launch when compared to normal operation. In the case of Dynamite this Boost is intended for testing / warming up the ride before opening it to the public, however it could be used to keep the ride operational in lower temperatures as well. Dynamite is roughly 3 seconds quicker through the layout when the Boost engages when the ride is warmed up compared to regular operations.

[@DanHalford41292]

An interesting use of variable-speed lift hills is to ensure that trains on separate layouts (or possibly different blocks in one layout,) come into close proximity with each other on dueling coasters. If I'm not mistaken, each train on Dueling Dragons (Islands of Adventure, Orlando, Florida,) is weighed once it has been loaded and the lift hill speeds are adjusted on-the-fly to ensure that weight differences don't counteract the 'dueling' aspect of the design. I always thought that was pretty cool, anyway 👍🏻

[@mason9146]

I want to show this comment to someone in 2018

[@janpenner2002]

Great Explanation! However, I think it's important to add a few things: Block Brakes are always designed to work even when there's no electricity provided to the System, e.g. due to a power shortage. This means that there are always pneumatic friction brakes found on a block section that are normally closed and need electricity to be opened and to let a train pass through. This way, when the ride doesn't get electricity any more, all trains stop automaticly at the end of the block section they're in. And if they are on the lifthill, the mechanical anti-rollback system prevents them from moving down the lift.

[@coasterbot]

All great additions! There's so many facts like these throughout the world of roller coasters. I think we've covered some both at least once somewhere in another video. Thank you :)

For those of you who are unfamiliar, a block zone is a section of ride that only one train may occupy. At the end of a block zone is a method to stop the train in case the block zone ahead is still occupied. This is the safety system that prevents roller coaster trains from colliding with one another.

[@TonyKimtheamusementparkfan]

For me, I love learning about the technical side of roller coasters, especially with block sections :) I saw ElToroRyan's video on Millennium Force and Top Thrill Dragster, and he was excellent at explaining the technical side of both of those Intamin coasters. Especially during the one he did on Top Thrill Dragster, he really went into depth of how the blocks are programmed when in automatic mode.

[@coasterbot]

ElToroRyan's videos are extremely interesting, especially learning about the quirks of the rides :)

[@MattMcIrvin]

As a former ride op, ElToroRyan cares deeply about block sections and includes a capsule explanation of them in most of his videos (to the point that it's become a running joke).

[@Varadict]

I'm glad you mentioned the continuous rolling block sections. 3 Major rides I can think that have this, especially one complicated one, is Maverick at Cedar Point. Which has multiple stations, and multiple waiting blocks for trains that when trains in the station begin to move, you can see trains overlapping other blocks and coming in very slowly over each other. Typically with coasters like this, you may notice more block sensors like on Top Thrill Dragster which accurately knows the position of each train between the Unloading station(s) and Main Loading Station(s)

[@VarietyEntertainmentStudios]

I love that you showed a ride with a really weird and untraditional block system for the thumbnail 😂

RollerCoaster tycoon Series (specially 2) made me understand how a block system works.

[@TheBigA]

If you’ve been on Rip Rockit then you definitely know how block sections work! There’s like a 90% chance you’ll get stuck on one since they run like 7 trains at once and anytime a train is slow to load, all the other trains have to stop all along the layout.

[@kevinmoser3095]

Thanks for this video. Now, when I play the Roller Coaster Tycoon franchise or Planet Coaster, and see the term “block section, now I have a better understanding of what it specifically means. I’ve seen the term before, but now I understand it better. It will help me when building great coasters in the future, while accounting for safety. Again, thanks. Btw, Planet Coaster is SO realistic.

[@coasterbot]

No problem, I'm glad to hear you've learnt something new which you can apply to some awesome games!

[@Dannyjones1]

THE SMILER - ACCIDENT EXPLAINED: The Smiler and it's block brake system worked to perfection on the day of the crash, but when the train go stuck in a valley, the engineer told the operator everything was fine and he chose to override the system allowing trains to be released from the chairlift. The engineer checked and had counted 4 trains which he believed were in safe positions. The operator failed to tell the engineer they had released another train just before during the busy period. This lack of communication ultimately caused the crash and bother engineer and operator are to be blame in my opinion.

[@coasterbot]

Thanks man, that means a lot :)

[@thrownchance]

6:35 since the lifthill is a blocksection for its entirety you could increase the number of trains to a total of the number of block sections. With proper timing and design of the rest of the rollercoaster you can always move a train (train C) from the block brakes before the station into the station while the train in front (train A) is on the lift. In the meantime the other train (train B) is moving on the rollercoaster as normal.

[@coasterbot]

I guess technically you could? But I imagine roller coasters aren't set up in this way :)

[@thrownchance]

@@coasterbot yeah, This would only be usefull when you would want to absolutelly max out the capacity of the coaster. Since usually with such a scheme you would have one waiting to roll into the station when the other goes out, you would increase the capacity by less than the theoretical 50% increase. And I guess you would have to be quite quick while loading the people onto the train.

I would like to point out something you missed. On most rides, if a train got stuck on a block brake for whatever reason, the park would typically have to send someone out to release the breaks once the problem has been fixed. Despite what games like RollerCoaster Tycoon and Planet Coaster would have you believe, most block breaks are not self-clearing. I say most because most B&M coasters actually do include self-clearing block breaks.

You probably should have mentioned why the smiler failed, ie the computer controlled block was over ridden. Like in building where most professionals study the disasters like fires and collapses for lessons, knowing how block sections can fail is important in understanding how they should work.

I didn't feel like this was within the scope. I purely wanted to explain how block sections work, not their shortcomings or how they're interacted with by ride operators.

[@Paolo8772]

I think @ 2:02 you meant to say 1863 rather than 1963. Also: @ 7:33 you mentioned that for a conventional coaster's MCBR the block brakes have to be high above the ground, but I think you might not have mentioned that the MCBR must be angled to slightly descend downwards going forward to allow the train's heavy weight to cause it to not only slowly go forward, but to complete it's circuit, as opposed to the launch block brakes which are angled to sightly descend backwards so that the train can roll back safely in the event rollback. (SHEESH! Now you've got me talking like Coaster Bot.) My sincere apologies Harry, but sometimes Coaster Bot can be infectious (did I just say that during these times?) Yes. Having said that: you know I love your content. Stay safe during these times.

[@coasterbot]

I did mean to say 1863, I'm not used to working with dates past the 1900s, there weren't a lot of roller coasters around before then! And you're totally right, a lot of MCBRs are tilted downwards to allow the train to roll off! I definitely should have slipped a sentence in there to cover this. But some do use kicker wheels to hold and push the train on an MCBR. Thanks for the comment and nice Coaster Bot impression ;)

[@Paolo8772]

@@coasterbot Kicker wheels? That'd be education, at least for me. Don't feel bad for the wrong century: When referring to a particular year, half the time I start off typing "19..." until I realize my folly as it's now 2020. Yup, even after 20 years... you get the picture. ;)

Kicker wheels are essentially car tyres places within the track which are used to transport the trains along sections of the track. You usually find them in and around the station and they are used to push the train into the station and out of it when it's stopped :)

Exhaustive and interesting video ! I still have one interrogation though. At 10:08, you show us a footage of Lost Gravity's MCBR : if the train is stopped at this block section, how can he manage to pass the dive drop wich is actually higher than the MCBR ? I can't see properly at 8:53, is there any magnetic system which could give the train some speed ?

[@coasterbot]

Thanks! And that's a really interesting point! I'm honestly not sure. Maybe the train can gain just enough speed to complete the roll, or operators have to give it a push to get it through, or maybe there is a magnetic system as you said to push the train forwards! I don't know but I'm sure someone familiar with the park does. Maybe ask around and let me know if you find anything :)

Many MCBRs will slow the trains down as they pass through them, as the next part of the layout is designed to be taken at a slower speed compared to the one which the train enters the MCBR with. Not all rides do that, but most do.

Wait! Developed in 1963 in the US? Come off it, Developed in the UK in 1839 and enshrined in UK legislation in 1889 with the Lock Block and Brake act forcing all railway companies to have mechanical interlockings between occupied tracks and points, block section working, and continuous brakes along the entire train.

[@hokyman]

I think it's interesting you show the Smiler a lot. That one had a terrible accident because a ride operator allowed a second train into a block section while another one was stuck, overriding the computer that had stopped that second train in the first place. Also, if anyone's a Disneyland fan (and probably Magic Kingdom as well) you'll know on Space Mountain that you've reached the end of a block section when you enter a straight section of track. Each one of those has a brake run and if I remember correctly there's 6 of them, allowing for a throughput of 7 trains (including the two lift hills and station section) at any given time. If you ever get stuck on the ride and the lights come on, you'll see all of these brake runs and the trains stopped at them. (I could be wrong about those numbers. Feel free to correct me if I am!)

Ha ha that's so cool, Factorio is a great game :)

[@ryanfrieman733]

Very informative, thanks!!!

[@coasterbot]

No problem, thanks for watching :)

[@revimfadli4666]

What about volatile vs nonvolatile blocks? What are the differences?

[@coasterbot]

I have no idea I'm afraid, I'm not sure I know what a volatile block is!

[@revimfadli4666]

@@coasterbot IIRC it was mentioned in one of your or other KZbinr's video, IIRC a nonvolatile block can move the trains actively(lifthills, drive tires) and control their speed, whereas volatile blocks can only stop trains at block brakes, and the trains' speed are at momentum & gravity's mercy

[@coasterbot]

Interesting, as I said I've never heard of that phrasing before but it sounds plausible! :)

[@revimfadli4666]

@@coasterbot update: I guess it was mentioned in Technology Connections' video about roller coaster block sections; your titles both have "roller coaster safety" in them, which made it seem like Mandela effect to me, lol.

[@anderemborujo5670]

Thanks a lot, great video;)

[@willowby]

there is a shockingly small amount of videos about block sections. Probably due to the simplicity.

[@coasterbot]

I think because it's quite a specific and unique topic that not many people even care to consider. But this video has been pretty successful so there's obviously an appetite to learn more about blocks :)

Can you do Inversions: Explained?

[@coasterbot]

What kind of things would you like to know about in a video like this? :)

[@kenepo4u496]

COASTER BOT The basic inversions like the vertical loop and corkscrew and some more unique ones.
