I was wondering if any of you track planning software junkies could turn Kent J. Johnson's Turtle Creek Central into a 4.5 x 6.5 foot layout... seen here... Amazon.com: Basic Model Railroad Track Plans: Small Starter Layouts You Can Build (Model Railroader Books): Books: Kent J. Johnson page 43 click look inside book and type in "turtle creek". It is the only part of the book available for viewing. I would like to see the 45 degree crossing removed and that middle section just becoming a spur. I would also like to see a passing siding on the right hand side, and a two track spur on the bottom left. I've tried my hand at the software stuff and I just can't get it. I just thought this might give someone a small challenge for fun.
