Hello all-- Just came across this trackplan, it is intriguing. However, a quick estimate of the grades given Mr. Graff's elevations shows some in the 5% range! I'd like to give it a go in HO for standard gauge operations with four-axle diesels, is it possible to adjust the elevations to keep the grades at a maxmimum 2.5% and still get over and under? I also have concerns about the length of passing tracks but I think that is more easily remedied. Thanks! Stuart
