The WORST Roller Coaster Accidents of the 2010's

There are thousands if not millions of coasters running as we speak without any problems. However, every once and a while one does slip up when it does it can lead to disastorous results. Today we look at the 5 worst Roller Coaster accidents of the 2010's...

The first one was really sad, because it could’ve been avoided outright if the staff had just listened to her when she said she didn’t feel safe. In fact, most of these could’ve been completely avoided if people had just used common sense.

Chimera’s accident is a huge example of park negligence. The park barely had proper maintenance on this thing and it was running much faster than it was meant to. You can see in POV videos of this ride that it goes *flying* through its midcourse break runs, and an accident on this roller coaster was unfortunately inevitable by the way it was operating.

as someone from the uk, the smiler one was just so tragic. like cause the uk has way less big themeparks than the us it effected the county. was so sad.

Regarding the smiler, the reason the 5th train wasn't noticed is because the engineers put it on, but didn't inform the ride operators. When it valleyed, the ride ops checked the location of the 4 known trains, and once located cleared the ride for dispatch and overrode the safety system. Since then, staff are now required to check all cameras to ensure the track is ALSO clear, regardless of if they have located the known trains

As someone who works for merlin, this is what I can say relatively confidently about the smiler incident.
Ride ops will have given the ride to engineering who will have added the 5th train, tested it and given the ride back to the ride operators for another set of testing. The empty train will have valleyed on the last test that the ops sent as guests were sent on the one directly after. After the train stopped on the lift hill, the ride op will have given the ride back to engineering (without seeing the valleyed train) to figure out what was wrong. The engineer called will likely not have been the same engineer who added the 5th train as the engineer thought that there were only 4 trains in operation. The engineer then checked for the other 3 trains and found them. He then will have assumed all was good and that a sensor on a block section had been triggered by something other than a train (things like leaves hit these sensors very often) and he will have overridden the alert and sent the train around the first section which the empty train had been sitting in. This is then when the incident happened
If you want to see what the engineers saw, the camera footage was released and is public on yt.
- I don't want to excuse what happened as there were still a lot of mistakes that happened but thought I should give a better picture as to what happened that day
*I also want to note that I am basing this off of protocol that is happening today which might have changed since the incident*

Part of why I feel New Texas Giant is overlooked is there is still feuding over fault. Gerstlaur blames Six Flags for unsafe ops, while Six Flags blames Gestlaur for the trains whose safety system gave the all clear before dispatch.

Thank you for putting this video together; I actually didn’t know about some of these. Knowledge is power and I think both guests and staff can learn a lot from studying the past.

[jonawesome]

Love how he hits the spot on making the video feel produced but not too produced. Absolutly amazing video and I always click on your vids when I see them

[lettuce]

I love how much work he puts into these vids. He takes his time to work on them and I love the editing lately. Your on a come up coastoons. Your gonna blow up at some point. Keep
Up the work man
Edit: love the choices of music too. Hell of a good job

These past two years have been absolutely tragic. The worst and most heartbreaking accidents are the ones that are totally preventable.

[FinesseBTW]

For further clarification, the accident on the Smiler was caused by a miscommunication between the ride ops and maintenance. Maintenence added a 5th train to the ride, but didn't tell the ride operators. When that train valleyed, the operators visually confirmed the locations of all 4 trains on the ride. Not knowing a 5th train had been added, they assumed that it was a ghost train. Ghost trains are common since the sensors on the ride are pretty sensitive. That is why they manually overrode the computer system which stopped the following train.

I'm not excusing what happened. I think knowledge is power, and the more clarification we have on what happened, the better

On the Quimera one, when it's relocated and the car is running in the video, when it goes on one of the loops it litterally shakes the whole loop

>doesn't rank accidents as to avoid making light of any single incident

[dademurphy]

Defo make a series mate, very glad to hear you mention the wind issue for smiler, it's something that gets glossed over in a lot of other videos

[Lloyd]

I know it's not a roller coaster but the drop tower accident in Florida was scary. what freaked me out was the ops were clearly confused and arguing about something before dispatch. if I see that I'm getting the hell off the ride!

[gamermapping]

Everyone probably knows this but I wanna clarify it just to be sure, The Smiler has always been the safest coaster at ATR and has been even safer after the crash (The Overiddes panel has been locked until someone higher than a ride op or engineer unlocks it) The machine itself did everything it was supposed to. Please don't worry about your safety on the ride.

[marrojas]

Adding to the Quimera accident, the investigation concluded that the ride wasn't properly maintained, and thus there was negligence in the part of the park. Because of that, the Mexico City Government closed permanently the park and revoked the concession of the operators of the park.

coastoons, i know you probably wont see this but i just want you to know your videos are awesome. your music taste is amazing and i love your humor and editing. keep up the great work man

[Weezer.Fan]

this sounds really dumb but thank you for putting different objects to help visualize how tall something was. I struggle with visualization but being able to see it in terms of an everyday object helped alot!

[HECKproductions]

being valleyed while another train is being dispatched and being dispatched while another train is valleyed somewhere both sound equally terrifying
