Chapter 168: Sealed blocks and stub tracks
Twenty yards of sealed blocks and stub tracks
Sealed blocks are two or three cars coupled as a unit. A pull or shove that would cut between them is refused, and a block is never humped or kicked.
Some tracks hang off another track instead of the ladder. The engine only reaches the back track while the front one is clear up to the switch, and the fouling point is marked.
20 yards, pars from 5 to 13 moves. Beside its theme, chapter 168 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.
