EuroTre Posted August 1, 2006 Share Posted August 1, 2006 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! Link to comment Share on other sites More sharing options...
SLUSHIE Posted August 1, 2006 Share Posted August 1, 2006 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. Link to comment Share on other sites More sharing options...
thomas2 Posted August 1, 2006 Share Posted August 1, 2006 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 Link to comment Share on other sites More sharing options...
verticalzero Posted August 1, 2006 Share Posted August 1, 2006 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.

Golfie Posted August 1, 2006 Share Posted August 1, 2006 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. Link to comment Share on other sites More sharing options...
stormrider Posted August 1, 2006 Share Posted August 1, 2006 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. Link to comment Share on other sites More sharing options...
trustkill22 Posted August 1, 2006 Share Posted August 1, 2006 ^^That sounds right. Removing of trains because wheel assemblies get to much stress sounds pretty good. Link to comment Share on other sites More sharing options...
EuroTre Posted August 1, 2006 Author Share Posted August 1, 2006 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. Link to comment Share on other sites More sharing options...
doitdumont1128 Posted August 1, 2006 Share Posted August 1, 2006 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. Link to comment Share on other sites More sharing options...
timetrial3141592 Posted August 2, 2006 Share Posted August 2, 2006 Speaking of FD3... The restraints could not have unlocked. The default setting for restraints is locked. The operators unlock them. Link to comment Share on other sites More sharing options...
bgwfreak Posted August 2, 2006 Share Posted August 2, 2006 When BTMR derailed at Disenyland I think the front wheel fell off or something like that which made the train slam to a stop. Link to comment Share on other sites More sharing options...
