Thanks for the come back. I also found the same sites and have found several layouts in other scales. I guess I'll just put track together. I would like to build this as a door track for my grandson. :dude:
I recall seeing an HO layout plan for Paramount Ranch in a recent issue of Model Car Racing Magazine. It was four lanes. I'll try to take a picture of it and either post it here or email it to you tomorrow. I also have a two lane sketch that I made years ago based upon the routed version of the track in Robert Schleicher's Model Car Racing book. I'll see if it will photograph also.
Hope these are legible. The four lane layout by Robert Schleicher uses 18 and 15 inch curves. The two lane is one I drew up with a homemade stencil probably more than 15 years ago and never got around to building. For the two lane layout unlabeled straights are 9" and unlabeled turns are 9" 1/4 turns. I tried to label the remaining track pieces. (It uses two 6" turns, eight 12" turns, and one 6" straight).
Hope this helps.
(the paper the two lane was drawn on was yellow to begin with! It hasn't yellowed with age.)
