Chapter 154: Placard spacing and the wye
Twenty yards of placard spacing and the wye
Placard spacing rules for outbounds: a placarded car may not stand at the head of the train or be coupled to another placarded car.
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 4 to 15 moves. Beside its theme, chapter 154 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.
