Wheels Falling Off

[EuroTre]

I keep hearing about these things that wheels on coasters fall off, ex. Steel Dragon. That would be a bad thing! Then I see coasters that come OFF THE TRACK! That would be an uneasy feeling! I wondering if it's possible for cars to derail. I know there are upstops on the wheels but if it really LIFTS off the track...

THAT IS FREEKING SCARY!

I don't understand you.

 

Coasters don't derail that often, and if they do they dont really come off the track they just kinda slide on it.

 

For car in the picture to derail two of the wheel assemblys on the same side would have to come appart, and thats pretty unrealistic.

Yeah some of the greatest coasters in the world have derailed... Luckily they will be reopened in August

 

It would seriously scare the crap out of me if the train I sat in derailes

[verticalzero]

The trains are ment to use the "Upstop" wheels on going over humps, as these keep the train or cars on the track.

 

The trains will never come off the track unless the "Upstop" wheels break or something snaps, you would know what happens next if your going over a hill or coming out of a loop if they did break.

That's because there is so much ejector air on that hill, the train wants to keep going up while the track is pulling it down. On a lot of wheel assemblies, there is a little bit of space between the upstop wheels and the track.

Correct me if I'm wrong, I think that extra space is so too much stress doesn't damage the assembly. It's like how some of the woodies have track that bends as it goes to absorb force.

^^That sounds right. Removing of trains because wheel assemblies get to much stress sounds pretty good.

Yeah, I made this post because I saw this picture and thought "Gee, that reminds me of some of the stuff I've heard about." I thought it was interesting.

FD3, with the rollercoaster crash, made it seem tht crashes and de-rails are common, but quite the contrary. Still intense scene. almost makes me not love coasters anymore. Almost, but not.

Speaking of FD3...

 

The restraints could not have unlocked. The default setting for restraints is locked. The operators unlock them.

When BTMR derailed at Disenyland I think the front wheel fell off or something like that which made the train slam to a stop.
