  1. Thank you for the article. I found it very interesting. Perhaps you can answer a question I’ve always wondered about. Why aren’t any of the manufacturers experimenting with some sort of dampener or shock system on their cars? It seems to me this would allow them to use wheels with a much lower rolling resistance and higher load endurance, with a decreased operating expense, while still providing a smooth ride and certain level of comfort for the passengers. Would the cost of maintaining the shocks simply negate the cost savings on the wheels? It seems to me that shocks should last longer than wheels. Thoughts?

    Thanks for reading ! You bring up a good point there and I am not entirely sure. Looks like the S&S free fly has a suspension or damper system but it’s on the support arms, not on the vehicle chassis itself. I’ll have to look into it. Maybe I can even ask a designer in one of our next interviews.

  3. We must remember that those roller coaster wheels are made of materials that break down over time and need to be serviced. Great post!

    Maybe none dumper/shock system could ever be instaled on any coaster just because the train never transfers it’s weight in the same direction as the rail/wheels, specially on looping/twisted coasters. The weight changes positions all the time so the dumper could absorb some shock but others could not.

  5. I savor, result in I found just what I was looking for.

    You have ended my four day lengthy hunt! God Bless you man. Have a nice day.
