Track Dimensions.

I have searched high and low and I was wondering what the average width of a coaster track is. Also, does anyone know the dimensions of rails?

I am sort of working on designing my own coaster on Mechanical Desktop 2005 on my lunch breaks and I would like to have an idea of the dimensions for track.

My guess is:
Average track width = spine 3ft, 4ft with the rails
Average rail = Radius of 3 inches

Dont quote me on that, because thats just a guess.

Hope that helps.:)

Thats strange? I was planning on making Top Thrill Dragster in my Autocad class this year. (O well great minds think alike)

On this can anyone give the distance (a rough guess) between the launch and break runs on t.t.d.

Arrow coasters have a track gauge of 48", The rails are 4" in diameter and the spine is 14" in diameter.

But why mechanical desktop?! Do you have inventor or solidworks?

I am a CAD designer for a paint ciculation company. This is what we use with AutoCAD 2004. So my resources are limited.

Luckily my best friend is also the IT guy here so I am going to look into some other programs. right now this coaster is nothing but words on paper.

Thank you for the arrow dimensions. As i am looking to stray away from Intamin box track. But I would not mind having those dimensions either.

I tried designing Dragster in AutoCad 2002 about a year and a half ago. It's really, REALLY hard to do if you want to do it accurately.

I hate inventor. I tried a coaster, and failed.

The normal width of B&M track is 42 inches.

I tried building Millennium Force in Inventor, and I also failed. It's way too complicated. I like AutoCad better.

Funkyjive, The launch cables are 497 feet I believe, if that helps you with anything.

I've been thinking about the rough dimensions. Aprox 2800ft(total length) So 2800-800 (up and down on tower) so I got aprox 2000ft left. 2000-925-925 (Station and launch/brake run) then the extra 150 will be the curve(unload section) and tophat and anything else.

But I still need a rough estimate on the distance between the launch and brake runs. Knowing that I can make a good guess as to where on the tower the track goes from vertical to starting to level off.
