Chapter 175: No-engine tracks and the wye
Twenty yards of no-engine tracks and the wye
A track behind a derail is closed to the locomotive. Cars can only be kicked or humped into it and never pulled back out, so each one has to arrive in order.
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.
20 yards, pars from 3 to 11 moves. Beside its theme, chapter 175 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.
