....Boy, I'd like to catch that....That is one of my interests in railroading.  Just how it {track structures}, are controlled, kept in place and all aspects of it, etc....Also the engineering necessary to locate it in the first place.  Usable grades, and still attain elevation to get across ridges and worse, mountains.
