The V-scale doesn't consider risk and is purely focused on the technical difficulty of the movements. [2] The V-scale is the dominant scale in North America, and it and the Font scale are the most dominant systems worldwide; beyond the easiest grades, the two systems can be almost exactly aligned in comparison tables.

[10] [11] The V&O was a bridge route, and most mainline traffic was to and from points beyond the V&O. 30-40 trains per day were needed to carry the V&O traffic. An important concept was that the use of walk-around throttles enabled operators to follow their trains from point to point and eliminated the doubling back and running in circles ...
