just wondering what you were insinuating with the comment about safety.
The rollercoaster in SM is old. And as such, it requires a regular maintenance cycle of constantly welding to stop cracking.
Sounds dangerous, right? Well, that's the claim some make. They say this constant need to weld is a sign that the coaster is about to have a spectacular fail and kill people. As a side effect of the constantly welding, the ride isn't as smooth as it could be. So, every time you ride it and feel the shaking, you're feeling your probably immediate death.
However, others claim that every coaster that old has a regular maintenance of welding. Steel cracks under repeated stress. It's what steel does. It is not self-healing. It needs welding. It's what happens to all coasters. The fact that they're conducting such rigorous maintenance and welding whenever they find a crack is actually a sign of its safety. Though, even these people will say it's really time for a new coaster. Welding can't go on forever as a fix. Eventually all coasters need new tracks, or, a complete rebuild.
