B&M Tie Spacing

Tuesday, June 18, 2002 10:41 AM
Are the ties on B&M coasters always spaced equally or are they spaced depending on how much force the track has to withstand?

It will be dictated by engineering and forces when they first designed the track, but the spacing is probably kept as even as possible to keep the effect going

Although I am definitely not an engineer, I think the ties are the same distance apart regardless to the forces on the coaster. This appears to be the case on all steel tracks, regardless of manufacturer. However, the location of the supports that hold up the track is certainly dictated by the forces the coaster exerts on the track.

The different types of Intamin track are a good example of this. See the CoasterBuzz article on Trackspotting, for an explanation:

What I was saying is that when the individual pieces of track were first designed, the types we can identify on sight as B&M, Morgan, Intamin, Arrow, etc., they were designed so that those cross braces are spaced to hold maximum loads on that section of track (about 6-10 feet depending). The spacing might change around complex twists and such, but they try and keep it even for both engineering and aesthic purposes

It looked like the older Arrow coasters had less spacing or more spacing in some areas I know I have seen this for myself. I don't think any companies do that anymore though and the track has been replaces on some coasters with reinforced track.

All ties seemed to be spaced pretty evenly on most coasters, I also agree with B&M Tycoon about Arrows Crossties. On the Demon at SFGAm there is a big gap in the cross ties on the first drop. Im not sure if it was always there or ended up that way when they changed Turn of the Century into the Demon.

I'm mostly wondering if the spacing on the two separate tracks at the top of this picture is an optical illusion or if the ties are actually different distances apart.

Its an optical illusion, differen't hieght variations provide a different point of view depending on the angle of view...

Actually, no. B&M tie spacing does differ at certain parts of the ride. In some points, it is a great difference. This topic came up today at SFoG, and we looked at Superman's Pretzel Loop and it was obvious that the ties were closer together. Im not sure why this is so, maybe forces, but they are spaced differently.

Yep, duelingdragonsrok11 is right...we were standing in line for SUF and I remember someone telling me that B&M ties were different distances apart. Being the analytical person I am sometimes, I had never seen this, and was wondering if it was true.

To my surprise it was, and it's quite blatantly obvious now. The pretzel loop at the bottom has very tightly packed ties whereas the top of the loop is spread out further.

Just goes to show how much engineering goes into these things!

Ya, question on PKI's racer when you come out of the station there is like a couple ties then 3 about an inch away from eatchother.
