Thank you for the info, hmmmm" I might go for the old school figure eight plan, I  think I can get away with a little smaller measurements if I go that way,

90 seconds spent with Google Earth shows that the real-life Tehachapi Loop is not a true circle, but averages about 1250' across. That's about 7'10" diameter in N scale. So roughly 47" radius. If you intend to model it accurately, the curves leading into The Loop itself are part of the signature track arrangement and would take up a lot of additional space. Almost no one has the room to model these features fully to-scale, even in N scale.

I’ve done a few Tehachapi layouts in different scales (HO here) and all of my clients chose to compress The Loop.

If you just want your tracks to loop over one another and aren’t intending to model Tehachapi per se, of course the radius could be much less.

Good luck with your layout.

Ulrich's reference looks pretty cool, and the archives are open to anyone, so check it out,

OR   gather the technical data, measuements, degrees, distance, grades, etc., on the actual loop and do the math.

PS. You'll have better luck getting into the Digital Archives with out logging in to the MR site.  And if your a subscriber to the archives, it's about the only way you'll get in.

The August 2015 copy contains a N scale track plan showing the Tehachapi Loop.

Happy times!

Thanks guys and have a blessed New Year!!
