Chapter 66: Placard spacing and tonnage
Twenty yards of placard spacing and tonnage
Placard spacing rules for outbounds: a placarded car may not stand at the head of the train or be coupled to another placarded car.
The engine carries a tonnage rating. Loaded cars weigh more than empties, and the engine cannot move a cut heavier than its rating, so big pulls have to be broken up.
20 yards, pars from 4 to 15 moves. Beside its theme, chapter 66 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.

* A par marked with a star is the best known line for a yard too large to solve outright.
