JRHcoasterki Posted June 8, 2012 Share Posted June 8, 2012 Hey! This is very random, but I was watching on-ride videos of just random B&M coasters and I noticed that say on Nitro, the track has the square spine such and such. But then I watched a video of Griffon and I noticed that the spine seemed wider but thinner so the rails were closer to the spine. Am I crazy, or does B&M have slightly different tracks on their Dive Machines? Or do they have several slightly different tracks on different coasters and I just don't notice it? I know this is random... But I was just wondering. Link to comment Share on other sites More sharing options...
KDCOASTERFAN Posted June 8, 2012 Share Posted June 8, 2012 There are indeed subtle differences in B&M's track depending on the type of ride it's designed for. Link to comment Share on other sites More sharing options...
XYZ Posted June 8, 2012 Share Posted June 8, 2012 (edited) I believe Dive Machines have a stronger track since the trains are very wide which means it is heavier per row than a B&M Hyper. Edited June 8, 2012 by XYZ Link to comment Share on other sites More sharing options...
JRHcoasterki Posted June 8, 2012 Author Share Posted June 8, 2012 Oh alright! That makes sense. Thanks! Link to comment Share on other sites More sharing options...
Ed Farmer Posted June 8, 2012 Share Posted June 8, 2012 On top of what has been mentioned, the thickness of the track spine can vary over the course of the layout. Based on forces, I presume. Link to comment Share on other sites More sharing options...
KingRCT3 Posted June 8, 2012 Share Posted June 8, 2012 The Dive's track is very different than the others : larger and the cross-ties aren't the same. But here's even a subtle difference between sit-downs and Inverted: Here, the cross-ties are straight. But here, they are gay rounded.

spinning man Posted June 8, 2012 Share Posted June 8, 2012 As mentioned from a previous post, the thickness of the box section changes depending on the type of forces the track will have to withstand on that section. These changes are on all type of coasters. But the ones where you can see the differences the clearest are on dive machines and on hyper coasters.

KingRCT3 Posted June 8, 2012 Share Posted June 8, 2012 ^ Yup, as you can see on Silverstar. Also, here's a video about their fabrication: Link to comment Share on other sites More sharing options...
Invertalon Posted June 8, 2012 Share Posted June 8, 2012 B&M does use different spine depth on various parts of the rides along with different tie designs based off the type of coaster it is. You will notice on B&M rides that use less supports and/or high stress areas, the spine will be deeper. Thus increasing the moment of inertia on the track (resistance to bending) in that axis. Thus they can reduce the amount of supports used, which saves money. Intamin has start doing this as well with their new track design with the double spine, which does the same thing. If you notice, compare the amount of supports on a ride like Hershey's new ride versus the older Ride of Steel's with the old design. The same concept can be shown with something like a ruler. Orient the ruler "flat" and you can bend it very easily. Now rotate it 90* so you are trying to bend it "sideways" if you will. It is now very difficult to bend. Same principal they are using with track designs. Deeper the spine, the more resistance it has to forces/bending. The equation used for calculating the moment of inertia explains why clearly. For a rectangle (shape of B&M spine), the equation is I = (bh^3)/12 ... b = base of rectangle, h= height of rectangle. Notice the height goes to the third power. So it greatly increases the resistance of the spine to bending. Link to comment Share on other sites More sharing options...
MagicAngel94 Posted July 7, 2014 Share Posted July 7, 2014 these are some parts of the track og Gardaland 2015 B&M Dive Coaster. In particular, I wanted to ask what is the piece of track with metal wings. can be a part of launch? Link to comment Share on other sites More sharing options...
KingRCT3 Posted July 7, 2014 Share Posted July 7, 2014 No, those are brake fins like those on Krake. Never understood why those were vertical when B&M always uses horizontal magnets. Link to comment Share on other sites More sharing options...
DJeXeL Posted July 7, 2014 Share Posted July 7, 2014 B&M only uses the vertical style brake fin on Dive coasters for some reason. Link to comment Share on other sites More sharing options...
thrillseeker4552 Posted July 7, 2014 Share Posted July 7, 2014 ^Specifically, the small Dive coasters (Krake, this, and possibly Efteling). Griffon and Sheikra both have horizontal magnetic brakes. When B&M eventually builds a launch coaster of their own, I can pretty much guarantee that the vertical magnets will be used. Don't really know why, but it seems likely.

TPDave Posted July 7, 2014 Share Posted July 7, 2014 ^ Could just be that this is a newer design and it somehow more efficient or economical than the older rides, so not necessarily pegged to the coasters size. It's not uncommon for incremental design changes to creep in over the lifespan of a product range like this. Link to comment Share on other sites More sharing options...
