What a given rise over a given run works out to as a grade, what that does to train length, and how much run you need for the clearance to cross over another track.
Every page here is computed rather than written, so the figures match the calculator that produced them exactly. Where a figure is a hobby rule of thumb rather than a published NMRA standard, the page says so. Every table is plain HTML you can quote.
