I am starting to get the idea of posting pics on the forum, hit the wrong button to add the info.

Coming along nicely with my Tehachapi loop version outdoor layout. I was hopping to have the top track on the tunnel 12 inches, but not to be it is 9 inches high.

The spiral grade is working out to be 3/8inches a foot, worked out well as the spiral length it 24ft on a 7ft diameter radius double track.

Where the pergola post is nearest to the grass may have to add in another couple of feet for tunnel 9 to get it right.



The Tehachapi loop track design has been redesigned and mover closer to the house now


Herb and Bernd let me know if the pics are too big.
