Chapter 3: The hump
Twenty yards of the hump
From the crest of the hump a whole cut rolls off one car at a time, each routed to a track as it goes, and the lot counts as a single move.
20 yards, pars from 3 to 6 moves. Beside its theme, chapter 3 draws on the running track, the wye and yard orders, with two breathers of plain sorting and extra cars. Difficulty runs as a sawtooth: runs of easy yards, a spike, a breather.
