Wooden coaster track dimensions

I've decided to build a 1/4 scale replica of a section of wooden coaster track, perhaps about 3 feet in length. I'm just doing it for the fun of it. It's not intended to be functional, but I'd like it to be scaled accurately. Perhaps my searching skills are pretty bad, but I just haven't been able to find a source for average dimensions out there.

Can anyone recommend a source for this info? Thanks for any help.

Google John A. Miller coaster patents. It's a start.....

Take a look at he Incredible Scream Machine: A History of the Roller Coaster. I believe it has what you are looking for.

I know there is a diagram in the aforementioned TISM:ahotrc but I don't think it has dimensions on it. in fact...nope, not even as much detail as I thought; it's just a diagram of the underwheel system. (p. 206). It's not even close to showing how the track stack is built.

I know the diagram you want. It's in a booklet that John Allen wrote that was published by PTC that describes how to build and maintain wood coasters. Question is, do I have a copy of it around here somewhere...?

I know that the stack is up to nine layers of 2x6-2x10 depending on the stresses involved, with the top two layers offset 2" ot the inside. Track ties are up to 4x4 and the track rests on the ledger boards (is not fastened to them). Track gauge between the centerlines of the road wheels is 43-1/4", between the guide wheels is 33"-34" and the upstop is offset to a width of 38". That way the upstop can ride beneath the flange formed by offsetting the top layers of track while the road wheels ride on top of the stack.

Wow, Dave, thanks so much for the information. This is enough to get me going. I apologize for the late reply. Life got in the way.

Gratefully,

Here is an article I stumbled upon a few months ago.

Can’t speak to the accuracy, but some cool wood coaster cross section info within…
