Roller Coaster Safety: How to Manage Too Many Trains at Once

Roller coasters are pretty neat, I must say. But they rely on passive vehicles holding fragile humans while zooming around at high speeds. That can be a tough thing to manage safely, but it’s not impossible. This video shows you a few ways it’s done.

  • I believe you showed the american eagle in your video. I worked that ride in operations and maintenance. 3 trains, one loading in the station, one on the course, one in the shed (area behind the station). If you didn't pull the train in from the shed fast enough, you'd get a "slow lift" and if you waited longer still, you'd get a "setup" which stopped the lift entirely, and would require maintenance to reset the ride. There was also a brake at the "barrel" (full 360° section at the far end) which actually used to be a manned station.

  • While older designs like Space Mountain may well use single block spacing. Modern coasters require two clear blocks between trains, this eliminates "single point of failure" issues by there always being two brake runs between any trains. -Signed Controls Engineer that used to do maintenance at a Six Flags.

  • EPCOT was always an inspiration to me too, especially the Carousel of Progress. There's a great big beautiful tomorrow, shining at the end of every day…

  • boy if you like theme parks that have such nice decoration that the ride elements are hidden, you should see the Efteling, it's a themepark based around fairytales and it has many beautiful rides that manage to hide the fact that they are simple rollercoasters really well..

    there is also a ride in complete darkness there, it is called the Vogelrock and i think it uses the same smart solution of complete darkness to have more trains on the track.
    they also have Villa volta which uses a combination of angled seats on a moving platform, and moving props to induce the feeling that the whole room is going upside down, i have actually gotten stuck with the safety bar in my neck because it lowered just as i was picking up the pendulum that i made to find out how much the room was actually spinning.
    but my favorite ride must be the Droomvlucht (dreamflight), it never goes faster than walking speed and it just cruises through this amazing fantasy landscape with elves and flying castles and loads of fake mist.. boy now i wanna go back to the Efteling..

  • "If these marbles were vehicles containing fragile and litigious human beings…." You say that like you've never been sued by a marble. If you're going to lie you should at least make your lies believable.

  • We were at Disney the year Space Mountain opened. The line was forever long and it kept breaking down. So those signs that say, "Your wait is blank minutes" didn't help much. My friend waited and took the ride. I did other things and didn't ride it until the next time we went back several years later. For the olds here, you know that was also when Disney used the ticket system.

  • I don't know why I can get so obsessed almost to the point of feeling like I'm addicted to a substance, learning about roller coaster and ride mechanical technology and also that of ride control systems like block sections, and watching the video you mentioned posted by someone else of space mountain with the lights on. You can hear the main panel operator calling out which block sections for the ride ops to go and get ready to push the train through. It's all just so fascinating. No other amusement parks have rides so complex and extremely well engineered like Disney does. 🙂

  • We were held on the first big lift at Big Thunder (WDW) for about five minutes, and then detrained to walk back down and on an epic hike through the innards of the ride. They gave us a bunch of free FastPasses and apologised profusely, but for big fat °o° nerds like us, it was the highlight of the day. Even my 4-year-old niece loved it, and snuck onto the track itself.

    We booked onto the “Backstage Magic” tour the next day. Well worth it.

  • The Whizzer (the image at 1:46) is an awesome ride with an equally awesome history. It is a type of ride with motors in the cars themselves, and they move themselves up the spiral lift hill, which was a space-saving feature if I remember correctly. It's at Six Flags Great America in Gurnee, Illinois, where it was built when the park opened in the 1970s. I highly recommend perusing it's Wikipedia page if you're into theme park rides or history.

  • So… block sections like in normal trains with "apply pressure to release" breaks like in trucks?

    I mean… all of it was already there, but someone had to put it all together, which is nice.

  • Thanks for the RCT shout-out. I was already thinking "block sections!".

    Fun fact: while the brakes are on the train, this is fundamentally the same method of collision prevention used on railways.

  • 2:03 The Racer at Kennywood, in Pittsburgh, Pennsylvania runs two trains simultaneously on the same track. The track is sort of a convoluted, folded figure-eight, causing the trains to switch platforms following each run. I suppose a collision would be possible if the ride operator failed to pay attention to an abnormally stopped train, but the operator would need to be negligent for the duration of an entire run in order for that to happen.

  • I find Mexican Coca-Cola to taste better and, overall, a bit cleaner than American Coca-Cola. It's probably because they use cane sugar in Mexico instead of high fructose corn syrup like here in America.

  • I love your videos on old tech and power outlets… but when you start talking Disney you’re talking my language! Keep making some Disney videos here and there!

  • This video definitely helped led me into the career I’m pursuing. Disney Imagineering or working for some other company designing control systems for amusement rides

  • This is precisely what Alton towers didnt do in the smiler incident, they accidentally forgot there was a train stopped in one of the blocks, and sent another one, filled with passengers
