Wood coaster track gauge? 4' ?

Waswondering what it is, from center of rail to center of rail (or leftcenter of running wheel to right center of running wheel). Looks to be4 feet, that's what I know Arrow always was. Seems like it might be toolarge an estimation. Anyone know for sure?

(was posted under nolimits forum, but think it's better here)

I always though the coaster guage depended on the ride and what the specs called for.

Sure PTC could always teak little specs (such as axle width) to match the particular coaster.

Have you read through the "wood coaster construction of track" thread? Some information there.

^ I have not, and can't seem to find it. Where is it? Thanks :)

Here you go.
