Why Roller Coaster Track is Filled with Sand

[Art of Engineering]

I had so much fun putting this whole video together, even though the animated graphics took me FOREVER to make. What did you think of the cinematic style intro!?

[GUTS]

Did you get enough compliments yet?

[Itz_Greenfield]

The Intro was very cool but it seemed unnecessary and that time could’ve been used better, I hope you understand

[In Downeast Maine]

@dabajabaza111 Agreed!

[Lewis]

I skipped the intro, honestly.

[Libby Butler]

The intro made me like

[Ben Roache]

While I appreciate the effort, if you're going to do a 7-minute piece about the sounds roller-coasters make you should definitely, definitely include the actual sounds that a roller-coaster makes into the video at some point.

[colorwayADDict]

Or y’all could make your own video and have all the sounds you want. 🙄 y’all bytchin over free shyt.

[WillKie]

@Art of Engineering if u were to do this again u should use nemesis at Alton towers as an example 🙂

[Whiskey w]

@bowlchamps37 I know you said that over three years ago, but would you perhaps marry me?

[CamdenKing]

yeah

[dirk diggler]

Just play this video on higher volume. Problem solved

[Exploring Abandoned Mines and Unusual Places]

Great job! As others have mentioned, it would’ve been nice to hear an audio sample of each type of coaster. The graphics were nicely done and easy to understand. You have a great voice, too, for narrating.

[Lee Macfarlane]

dont tell me all manufacturers coasters have distinct sounds and then not let me hear them

[kuri garu]

Honestlyyyy

[TheSmasherOr ?!?!?!?]

@idkwhattoputhere your biased. No

[idkwhattoputhere]

Arrow's have the best sound. Prove me wrong

[Aidan Armstrong]

@Sami smh

[Sami]

Sami I came first 🤷🏻‍♂️

[Tbone]

By having the sand in the structure, would this also make the structure last longer and require less repairs? It seems that the sand absorbs the sound which means the vibrations would do less damage to the structure of the coaster over time.

[sharkheadism]

No

[Tbone]

@Balázs Őrley Interesting point. Perhaps the art of engineering as a video to consider making :)

[Balázs Őrley]

Travel With Tbone I was just wondering about the opposite. Wouldn’t the sand act like, well, sandpaper and eat away the inner walls in the long run?

[wooden coyote]

When I saw the title, I guessed that the sand would be something to do with weight and stability. Sound never occured to me. Thank you for sharing, this was very interesting to learn.

[viddork]

Funny, because sound dampening was the _only_ thing that occurred to me. Never thought of stability.

[Hammad Sheikh]

Regardless of the sand, I’ve been on leviathan and stood underneath it at the entrance at CW. The sound is definitely a cool feature as it sounds like a roar. Moreover, the screams of the passengers going by is icing on the cake.

[Armedez]

Leviathan is one of my favourite rides I've ever been on, and can't wait to try Yukon this year.

[Nincadalop]

*Moves into house across a roller coaster park "Who put that there?"

[Thomas Thedoubter]

These sort of people always wonder why the houses next to the airport are so cheap.

[Jason Darling]

You have to be absolutely brain dead to move near a race track, airport, or an amusement park and later complain about noise. We lost a race track years ago, that had been there for decades, but a new subdivision was build and the Karens began complaining about the noise. The track closed, and soon most of the local businesses closed too. But hey, the retards got their quiet, in the form of a ghost town.

[SpencEpix / Spence Severt]

Halsare Snowpaw I think Nincadalop meant that the theme park was already there before the houses were made.

[SpencEpix / Spence Severt]

I mean it’s called a theme park but... good enough

[ZT]

*ahem* Alton towers *ahem*

[tharbrick]

How can you talk about an iconic sound and then not letting us hear it? Gaargh

[Topher Wilson]

If you want to hear the sound, look up the riddlers revenge off ride six flags magic mountain and you can hear the noise distinctly. It is one of the only coasters made from B&M that still produces the famous noise.

[꧁ ꧂]

He needs to remake the video with sounds. Boom another viral vid

[BBK Zeke]

That's how iconic it is he didn't need to add it.

[Maximilian Y.]

pretty disappointed that the sounds of different sounds of rollercoaster are not showcased...

[AnduRo]

same

[Shawn Pitman]

@Mark Locy the sounds of the rollercoasters aren't copyrighted....

[CheesecakeLasagna]

I agree.

[Stoney3K]

@Bubba Given the way the box section at the first drop was constructed, I'm not surprised. The big box section acts as a waveguide which is resonant in very low frequencies (because there's a large volume of air in the box), and it's attached to a concrete foundation, so the noise from the coaster would be blasted right into the park's ground area, as steel is a perfect sound conductor. Adding the sand would put the resonant frequencies in a much higher area of the frequency spectrum which is not able to travel as far through ground material (e.g. dirt or concrete).

[JP]

Leviathan and Behemoth are dope, but when I was little and there's no queue, I just keep riding Wild Beast by staying on the coaster.

[Brian Rose]

It would be very interesting to "hear" the actual rollercoaster before and after

[Tsutaru]

I'd love to see a video detailing more differences between track designs, and what the signatures of the different companies are. I'd have a lot of fun visiting parks and trying to guess who was behind each coaster!

[Alex Stevens Creative Media]

Just came across this channel, it's great! Short videos, interesting content, and well made animations

[Spencer Brooks]

I've been to Canada's Wonderland more times than I can count and I can personally say that even after the sand it still is incredibly loud! Also the first drop is so fast and so steep it takes all the blood away from your eyes and you actually go blind for a few seconds! Good video though!

[Joshua Doll]

That intro had my nostalgia on full blast of when I would build all sorts of different roller coasters in RCT 2 and then ride them from the perspective of a someone on the roller coaster.

[Nick]

I live very close to wonderland and have a season pass, I never really realized that the ride noise had been changed I really don't think that the noise changed that much. Thanks for sharing, and great video!! :D

[homestar92]

I love the old B&M roar. It makes me sad when I hear the muted sound of the sand-filled ones. Mantis... er, Rougarou and Kumba have some of the best roars out there.

[Richard]

Your videos are wonderfully informative. Have you considered helping your non-metric viewers out by displaying the conversion values on the screen momentarily? Thanks!

[Dragon Fire]

As a coaster enthusiast, I was impressed with the professional of the video. You got all the manufacturing companys right. You obviously did your research, so kudos to you. Great video

[crazeeeconman]

@Mr. Blue Yeah exactly lol

[Mr. Blue]

@oJalen - why can't someone with the name "dragon fire" be a coaster enthusiast?

[Dragon Fire]

@oJalen what's your point

[oJalen]

his name is dragon fire & y’all believe he’s a coaster enthusiast ???? think

[grnsgottaM]

Crazy that they could support that weight without redesign, the sand has to weigh a fuckton!

[Paul Sild]

Thank you for an interesting and informative video! I particularly enjoyed the well articulated explanations with diagrams.

[jarod]

I wish you stated exactly how effective the sand solution was. I would like to know the difference in decibels before and after sand was added. If anyone knows or wants to do some research to find out, please let me know!

[Thoroughthoughts]

Leviathan was my first roller coaster, and my last. I thought if I conquered the biggest they would all seem small, instead I scared the shit out of myself to the point that I just ate funnel cake to ease my bruised ego for the rest of the day while my friends blasted through each coaster and I was stuck on the sidelines holding their stuff.

[Craig Reustle]

I want to hear one with the box AND the rails filled with sand. I also wonder if the sand would turn to powder after years of vibrations.

[Hollywood1127]

I have never understood how people can move right across the street from a busy theme park and then complain to the county about noise and traffic. Make them deal with it.

[shining Amaterasu]

people do the same about race tracks, its why laguna seca has to announce races 3 weeks in advance and cant have any races during some parts of the year. (the houses were built after the track)

[hackerman]

people moving close to military training grounds and complaining about seeing tanks and guns. people moving close to a university campus and complaining about partying students. people are stupid...

[Connor Branscombe]

@RipleySawzen Yeah thats how democracy works, just because one dude wants to be an asshole and ruin things for the 99 doesnt mean he can lmao, cry harder.

[Andrew]

Same with racetracks!

[RipleySawzen]

@gav com _tyranny of the majority lol isn’t that just democracy_ Exactly. Like if I had a farm, and people moved in next to it. Then 20 years later they vote to close my farm because they cannot stand the manure smell in the spring. (Real life story.)

[manstang351]

Cool video! I wonder how the mounting points feel about this extra weight? Do they strengthen those as well to compensate for the extra weight?

[Glenn Huber]

Would love to hear a before and after audio, this was real interesting

[Rob Schmid]

Has the sandblasting effect been totally overlooked by the engineering teams on this? Will the sand being vibrated in the box tube or in the rail not cause premature failure due to sandblasting effect?

[sheldon Reddy]

Appreciate the work put into this. It's a very long video to explain a very simple concept though.

[canadademon]

This is such a common issue with home buyers. I grew up next to train tracks so I was used to 'em. But people that would buy houses around us would constantly complain in the newspaper about the noise of the trains. Like... what do you expect them to do? Move the tracks? People are stupid.

[Connor Branscombe]

@Obunni It really ain’t that simple bud, If it was CW wouldn’t have designed Yukon to be quiet

[Obunni]

@LovableCoolGuy It’s a theme park! It’s most likely going to have to grow and evolve with the times and create new coasters, so it’s a given it’ll probably get noisier. If people don’t want that, they shouldn’t knowingly move to house across from it. It’s that simple.

[Bewix]

@IstasPumaNevada Lol still is completely unreasonable, sounds like you're one of the idiots that live next to a theme park

[AlterNate]

We're only human, it's only natural for us to address what bothers us 80% of the time. Unfortunately some people don't think until it's too late. They're probably thinking: "Oh how convenient, I live next to a [train/theme park] maybe I can use the [train/themepark] to [get to places quicker/have fun.]

[LovableCoolGuy]

I think you're discounting the element of *change*. It's more like living next to a busy road that you can tolerate, but then they decide to upgrade it to a highway. When someone changes it afterward, the situation is now reversed - the residents were "there first" as it were and it's specifically the new roller coaster itself that's the issue, not the old theme park as a whole.

[1genius1]

I live a bus ride away from Canada's Wonderland. I've been there in 2012 and 2014, riding on the Leviathan both times. CW said that the Leviathan (which was notorious at the time) goes as fast as 148 km/h. Also, the Yukon Striker actually opened this year.

[R Bryant]

The movement of the sand particles against each other will ultimately turn those sand-filled tubes into dust filled tubes which will provide significantly less sound dampening. (in my humble opinion)

[Karlee Slattery]

Wow! Super interesting. I live 2 hours from Canada's Wonderland and have gone my whole life. I love hearing these behind the scenes bits

[RT Arts]

As a person that lives very close to Canada's Wonderland, I personally liked it close to me as I can see all the rides operate.

[Momoniji]

Imagine picking your location next to a theme park then getting mad about the park.

[TRiG (Ireland)]

The video suggests that the park already existed, but the roller coaster was new

[Dave W]

@IroAppe like race tracks

[Dave W]

they do it with race tracks all the time , thats why street racing is so rampant

[Roberto Seaturd L]

@LiveTrash yep they are, we had morons that moved to our ski resort and complained about the trail groomers and snow making equipment at night, Jackasses be gone !

[Randy Sanders]

My grandparents had a vineyard since the 70's and we had to shut down our yearly harvest parties because a southern California lawyer moved into the property over and started complaining.

[racinglightning01]

You ever wonder if they thought about that aggregate, that they've introduced into the center of a constantly vibrating structure, is doing to the inside of those beams?

[Masaharu Morimoto]

Levithan is truly a terrifying experience! Highly recommended!

[Sean Riley]

I wonder if something else could have been used. Maybe something lighter like spray foam or coat the inside and outside with truck bed coating. It’s been proven that coating a room with Rhino Lining can help make it explosion resistant.

[Charlie W]

Great Video! I love the animation and how you explained all the aspects of solving the problem so everyone could learn something! A couple clarifications I want to make is that this was not a new solution, and B&M have had this as an option to parks since the early '90s, usually with pea gravel rather than fine sand, since it is cheaper, but Leviathan was a special case with it's large spine lift hill structure and your facts are correct as far as I know. This has certainly become a more popular option in the last decade. Another thing is, though this is beyond the scope of this video, adding sand or gravel also reduces sound by shifting the resonant frequency lower by increasing the mass of the structure, causing a great decrease in the gain of the system. Also, sorry, this just caught my eye as I am watching it again, I have not heard the term "Fin Plate" before, usually a fin refers to a flat plate in line with the direction of travel. Think of LIM stator fins, brake fins, or fins on a fish. We usually refer to the plates you are referring to as Cross Ties, Rail Ties, or just Ties (In America at least, B&M I would assume might call them des braces?) Sorry to give you a page full like this, I really honestly enjoyed this video! I'm Subbed. Keep up the great work!

[Art of Engineering]

Thanks so much for the additional insight! The fact that the additional mass contributes to the noise reduction is pretty interesting. I honestly can't recall where I first heard the term "fin plate," but I've just gotten into a habit of calling them that. The term "tie" makes a lot more sense.

[Phatpineapples]

I’ve been to Canada’s wonderland 30 times and I go on the Leviathan 3 times every time I go If you think it’s loud now try hearing it before they filled it that thing would give you tinnitus

[M M]

Hopefully full of the nice smooth sand that doesn’t bind very well, not the limited resource of coarse sand needed for glass and concrete

[WolvenSpectre]

With the rising cost of sand and supply chains becoming more questionable I wonder if they may move to shock absorbent polymer balls in the future. More of them are being made from non hydrocarbon sources and are getting cheaper. Just a thought.

[Robert Kirkham]

Wish my headphones were filled with sand before your intro song ruptured my eardrums

[ZT]

Oof

[Phoenix Smith]

900th like

[NEONProductions]

Uhh I don’t think that’s how it works 

[Lane Williams]

6:10 It is a clever yet simple technique and perhaps will be implemented more in the futur-*LOUD ASS MUSIC*

[Hamish M]

Please make more roller coaster based physics and engineering videos, that would be great!

[Work is fun...]

My questions would be , what about moisture retention, and, what kind of wear would the box beam receive from the sand due to the vibration?

[Pedro picapiedra]

Great video, really interesting but I would have liked if there was some kind of comparison between the two kinds of Rollercoaster. Anyway I understand the struggle to obtain fotagge of that and make a fair comparison.

[Berkana]

Could you do a video on the plausibility of using a roller coaster style hill or drop tower system for public transport? How plausible would it be to build a commuter coaster network with multiple parallel tracks, completely passive trains, with all of the propulsion done by putting energy into the coasters by pulling them either up a hill or pulling them backwards up a drop tower? How would the cost compare to the currently favored system of powered subway cars? How many parallel tracks would be needed to give the same commuter throughput without risking safety issues? How far could a roller coaster train actually coast? Would ballast be needed? Could one big drop and a slight grade to the track be sufficient to coast commuters across San Francisco bay? What if the trains were covered so as to be extremely aerodynamic? Also, how does the duty cycle of a subway compare to that of a roller coaster working full time at a busy amusement park? If there were a commuter coaster system, I would actually enjoy the commute.

[Slash Teh Flygon]

I only just came across this video, and as an avid rollercoaster finatic, I'm glad that I watched this! You learn something new every day!

[Isaac Akhigbe]

I use to live right across the street from Canada’s wonderland. This was before the Leviathan was made. The rides were still not that big of a disturbance as they were all inside the park. At the time, the behemoth was the loudest coaster but since it backs the highway, it really causes no one any trouble. Now I live about 7min away from wonderland. I had always wondered why the Leviathan was so quite until now. When you are in the park bellow the Leviathan, it is pretty loud. But once you are about 300-500m away, the noise is reduce greatly. In fact, once you are at the far end of the parking lot (closest to the road) the noise basically gone. You will have to pay attention to hear it. The closest houses are about 1-3km from all directions and I haven’t heard anything about noise complaints. In the summer time when the park opens, I will try and post a video with the noise of the roller coaster now to compare.

[Josh B]

Good video, but PLEASE PLEASE PLEASE do NOT make the opening sound that loud. If you have an audio meter when you are editing the sound should be at an average of -12dB. This gives it room to "breath". But whatever you do don't make music or sound effects loud like that. Thanks.

[Branden Anderson]

I think his lisp hurt my ears more than the song being too loud

[H LO]

Ur a virgin

[琥珀]

*breathe But yeah, what this guy said. Fuck your intro.

[Spiritual Dawg]

Josh B facts this shit can break ur spreakers

[Kyle Atkinson]

I think a lot of people are trying to mimic modern movies, which blast sound effects and music, but have quieter spoken audio. I find it annoying enough in movies, but when I want to watch what is basically a documentary, I expect the spoken audio to be louder and the music to take the backseat.

[SumDumGuy]

This is a pretty cool video. I always loved the way the Incredible Hulk coaster in Orlando sounded and now I know why.

[SaxxSam]

I've been to Canada's Wonderland many times and I can say the leviathan is loud but not loud enough to go to the neighborhood as much the loudest part is people screaming 😂 and idk about the Yukon striker because it's is Brand new and is gonna be opened this year

[josh carter]

I may be incorrect, but wouldn't a foam ( like great stuff or the like) have worked & been less invasive to the structure when applying. Drill a small hole, add the proper amount of expanding foam, patch, weld or plug. They can be quite dense & lightweight. Just a random thought that hit me.....

[Autumn]

I'm gonna be honest, if you're going to move into a residential area knowing it's across the street from an amusement park, you probably shouldn't be making noise complaints when there's noise coming from a big amusement park.

[Garrett]

I feel the words “safe” and “reliable”, when talking about a rollercoaster, go very hand in hand.

[Todd Crookham]

Without watching the video I'll post my thoughts on why the tracks are sand filled! First (Mass damping) the pull and push in all the directions exerted upon the tracks by the cars are extreme and the extra weight of the sand helps to counteract some of that movement which over time causes metal fatigue which would eventually lead to failure! Second (Vibration) sand can reduce unwanted vibrations which would lead to a smoother ride experience! Third (Speed) by reducing track movement and vibration you reduce parasitic loss of energy which results in a retention of more of the energy the cars started with at the top of the ride.

[BAT BOY]

Silver Bullet at Knotts Berry Farm is a good example of a coaster that uses this noise reduction method.

[Mark Santos]

ok youtube i'll watch this today...

[Izumi Shimomura]

Yes me too

[CoolTheFool]

Big youtuber virtually no replies?

[Master Civil Engineering]

Watch here bro

[Tobias Graf]

Really good video and well explained. Thanks for shearing!

[iCocoDee0]

I watched the into to this video and realized I’ve been on every single one of those rollercoasters. Me and my dad are rollercoaster junkies and travel all over just to do coasters

[MisterMarshall95]

This is also noticeable in PortAventura,they have two rollercoasters built by B&M, Dragon Khan and Shambhala. Dragon Khan has no sand neither inside thespine nor the rails (in order to make the ride "roar" like a dragon everytime a train is moving) ,but Shambhala has the inside of the rails filled with sand.

[R4KU1130]

If any of you have been on Great Beat at Hershey and wondered why it was so loud it was because of the lack of sand in the rails giving it its signature bear roar noise ;)

[Dan Ruegamer]

Spent a ton of time at Cedar Point this past season and was curious what made Gate Keeper the quietest ride in the park. Maybe next year they can poor some sand into Raptor.

[Josh B]

I feel like spray foam would be a lighter more efficient way to have do this. It would be more pricey though.

[missXspencer1]

Imagine asking a theme park to quiet down as opposed to just moving away from the theme park. Sidenote: I think I would love to hear a lease's worth of coasters.

[ants in my eyes]

So he’s not going to include a single real sound from a roller coaster?

[Isaac Akhigbe]

*Good Vibes* I use to live right across the street from Canada’s wonderland. This was before the Leviathan was made. The rides were still not that big of a disturbance as they were all inside the park. At the time, the behemoth was the loudest coaster but since it backs the highway, it really causes no one any trouble. Now I live about 7min away from wonderland.

[William Ambrogio]

I was wondering if as time goes on after thousands of cycles with high sound and vibration that fatigue and cracks might develope. That the sand would dampen this vibration and allow a longer service life ?? Great Video thanks William Orange county, ca. usa

[Quent K]

Honestly, I really hope they never do this to diamondback at kings island. Diamondback makes all of the best coaster noises: The loud click when engaging with the lift hill and exiting the final brakes The rollback brakes that resemble the sound a train makes The rattling sound heard when bottoming our The roar when it’s going down the track The B&M pulsing brakes

[FTLNewsFeed]

Thank You Engineering. It's due to trust in human engineering that I attribute my fear of rollercoasters abating. I still enjoy the thrill and the ride, but I remind myself everytime that the car is ascending the first hill that humans engineered and built this ride with my safety in mind and that the odds of anything bad happening, which is where the fear comes from, is so very very small. It helps me to actually enjoy the ride instead of living in fear of it.

[Tom Hardware]

This has been known in the audio industry for a long time to fill hollow speaker stands to reduce unwanted vibration. They couldn’t figure this out? Water would also do the same thing but would be more corrosive.

[Marc Marshall]

Fascinating! I'd heard of this already, but I didn't realize Leviathan was the first coaster to have this method of noise reduction implemented.

[Jeffrey Seifert]

@Based Shrine I believe you are correct. If Talon was not the first, then it was one of the first. Sound dampening started long before Leviathan.

[TravelWithGrant]

It was not the first. Not even close actually. All of the Busch Gardens Williamsburg B&M's have had sand filled into its rails due to complaints of nearby James City County and its high scale golf course. Many roller coasters have sand filled rails/beams

[Freundlicher Mensch]

I don't know which one was first but I know for sure that Black Mamba in Phantasialand also got Sand in the structure.

[Based Shrine]

Oh i thought talon at dorney park was

[Jamie C]

duelling dragons at universal; were the first

[Akiva Feinstein]

Does this sand introduce a chance of structural damage from corrosion? With the sand preventing evaporation of water that gets into the beams?

[blueline]

did they determine by how many decibels the sand reduced the sound?

[ة]

blueline they probably did, just find out

[Cameron w.]

Dude super impressive. Very well done. This is interesting because it reminds me of a case study i read in a business law class. In my city we have an airport which is on the outskirts of town. There is a unique community of houses in the area which is right by the airport. Someone bought a house there and then I believe tried to sue in the future because of noise complaints. They lost though because they should have known it would be noisy moving into an area right beside the airport. I think that’s how it went... it’s been a minute lol.

[Super Nova]

Kumba at Busch Gardens makes a really loud roar. You hear the chain lift getting louder and louder and then there is a moment of silence and you hear Kumba thundering down the first drop to go over the first loop. It’s an iconic sound that sends a chill down your spine and you can see it on the riders faces as they wait their turn.

[Authentic]

Let me make it quick. It makes it quiet. An example would be Talon, I believe people complained how it was loud or how it was near a neighborhood so they put sand in it to limit the amount of noise. I think the wheels also make a difference in the sound.

[Scott Dobbs]

Thank you for saving me 7 minutes of jabbering.

[Sam]

Yeah I rode talon recently and it was extremely quiet actually. Almost calming up there.

[Matthew P.]

Thanks. Saved me from a 7 minute video with an entirely too long intro.

[Vincent Ferrante]

Yes the wheels also play a role in the sound. Nylon wheels roar, polyurethane wheels are quiet

[Ben L]

Yeah, now that I think about it Talon is an extremely quiet coaster. All you have to do is to compare the sounds from Raptor at CP and the difference is enormous. Thanks for that tid-bit, I wouldn't have thought about that if you hadn't said it!

[David Yisrael]

Aside from noise the additional benifit is that its great for the structure itself. Vibrations lead to cracking parts and fatigue and failure. So they kind of hit 2 birds with one stone. I mean, sand.. Wait... What?...

[Al Bixx]

I wonder if expandable foam worked, foam is lighter than sand but sand is cheaper I guess.

[sed8me]

6:11 - love what ya did there. 🤣 Tho I do wonder what if any charge &/or errosive force rattling particulates might induce..? What "sand" was/is in use? Anyways, tip notch video 👍

[Brotang Youst]

The same thing happens with race tracks here, the tracks originally built out of earshot yet eventually people build nearer and nearer to it till the complaints start. Then the track gets restricted and eventually shutdown

[Joy Shyngle]

It might be a moot point and totally redundant, but the Kumba coaster at Busch Gardens Tampa Bay was intentionally designed without sound dampeners to imitate the sound of roaring which is what Kumba loosely translates to in the Kongo language. You can most definitely use that ride as an example of how insanely and painfully loud coasters without sand filling or other dampeners are. Standing anywhere near that ride is a rough experience for your ears and riding it is even worse 😂

[CriticalthinKing]

Great, water holding sand (hello rust) that 'sands' down the thickness of the steel every ride! Super short- term solution.

[Yerva]

Great video, the only thing I would add is the sound of sandless rollercoaster and the muffled sound for comparison

[Jeremiah Jenkins]

Woah woah woah, first off I live extremely close to Canada’s Wonderland, literally in the neighbourhood that you pointed to early in the video. To put things into perspective, people here do not really complain about the loud noise of the Leviathan. Also I’ve been seeing comments about how people moved to my area, beside a theme park, and complained about the noises of the rides. My counter to this is that the only ride that makes a noise that could be heard from far away is Leviathan. So technically the residents do have a right to complain about the noise, as they moved to the community before the construction of Leviathan. But do remember that close to nobody actually complains about the noise. If anything we complain about the traffic lmao.

[yukaira]

Very well put together! Shame there were no sounds though

[Fireman Joe]

Right off the bat I had concerns about a roller coaster that hangs over a parking lot. What are the chances that someone would purposely damage them since it’s so assessable?!

[Ev an]

I have been on this coaster before this happened and as well as it happened. I didn’t notice a difference seeing that there was quite a difference in time between the rides. I mostly remember hearing PFFFFFFFFSHHHHHHHHHWHHHHHHH from the air speed.

[ratoneJR]

There are some really talented engineers out there. BTW... it's really sad that ADULTS cannot be held responsible for their poor decisions.

[Chaddwickg]

Love the sound of a B&M coaster!!! #nosand

[horseshoe]

I love the sound of After Burn at Carowinds. After Burn is actually my favorite coaster at Carowinds. Yes, even over Fury 325.

[Aaron Fulton]

It’s coarse, rough, irritating, and it gets everywhere

[v8trauma]

@MasterDanMonkey Videos Nemesis Alton towers uk, or is there another one? An old mate of mine put a couple up there, the stories he told.

[john]

@ABBAbeth the hamster I was thinking more along the lines of ductape! Not sure if there is a solution out there,probably best to look at ear plugs

[ABBAbeth the hamster]

@john I've never heard of the second option (no pun intended). It sounds interesting to try. (I've already gotten custom ear plugs and filters from an audiologist who insisted on the musicians' variety, and all those did was eliminate the background noise, which made the problematic noises even worse with nothing to balance them. Strap-downs sound interesting, are they some sort of add-ons to existing headsets? If so, I'll have to try them out.)

[David Brown]

My guess for the sand before i watch: From the sheer force of the vibrations, and how they go down it would be unsafe for the poles, even if they are titanium. The sand will stop vibrations and will keep it in shape for a very long time.

[sharkheadism]

I was pretty peeved that you didn't include the sound of the roller coasters. However, when i realized you're just starting out with youtube i gave you a free pass because the rest of the video was so well done. Keep it up brother!

Hershey park has a coaster called the Great Bear. The sound of it was the whole sell of the ride from the beginning. But it's in the middle of the park so it doesn't cause issues for residential areas

I wonder if that potentially abrasive sand, vibrating around inside those steel structures, could over time, cause an invisible and dangerous weakening of these structures?

Was just at Knotts and noticed Silver Bullet is so quiet compared to the B&M's at Magic Mountain. Can anyone confirm that Silver Bullet has sand inserted? This is a cedar fair park as well.

Lily Sandoval I’ve been fascinated at the unique quietness of Silver Bullet, I guess this is the reason why!

[Lily Sandoval]

Silver bullet is so smooth and quiet it’s so insane lmao

@The Hawk you couldn't take less than 5 seconds to put, "Six Flags"? Lol. No hate, just sat Ying

The problem was never the sound, it was the houses a parking lot away from an amusement park

Sand would reduce the vibration that the box beam is emitting, But it would also in effect “sandblast” the inside walls of the box beam...Over time gradually removing material and weakening them...

Do we by any chance know what type of sand they used? The round, sahara desert sand due there not being a need for the sand to bind to anything. Or did they use the coarse beach sand that we use in construction, of which we have limited availability? I'm just guessing that they probably used the coarse sand due to economies of scale, even though the sahara desert sand is so large in quantity, not many wholesalers sell it.

True engineer here: It also avoids buckling of those large hollow sections. And/or fatigue due to buckling effects. Cheaper than welding stiffeners on the inside. True engineer out.

Excellent video, it was well researched and well edited! Really enjoy the accurate insight and you got the manufacturers and parks on point. I'm flattered you chose to use some of my footage to illustrate your comments. Thank you for giving credit, and congratulations on your successful video! Subbed :) Philippe-Minh

I thought I recognised some of the footage! Nice one my dude :)

Today I learned that the rails that roller coasters move along are often alarmingly hollow.
