Chapter 183: Tonnage and hidden waybills
Twenty yards of tonnage and hidden waybills
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.
In the dark a car’s waybill is hidden until it has been pulled. Goals still use the true destination, so par allows a look or two.
20 yards, pars from 6 to 16 moves. Beside its theme, chapter 183 draws on the shop, the helper and placard spacing, 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.
