Chapter 209: The wye and the hump
Twenty yards of the wye and the hump
A wye turns the whole cut in one move, reversing its order and the facing of every car. Some cars must stand facing the bumper at their destination.
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 11 moves. Beside its theme, chapter 209 draws on outbounds, tonnage and the shop, with two breathers of plain sorting and extra cars. Difficulty runs as a sawtooth: runs of easy yards, a spike, a breather.
