Chapter 58: Sealed blocks and no-engine tracks
Twenty yards of sealed blocks and no-engine 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.
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.
20 yards, pars from 3 to 12 moves. Beside its theme, chapter 58 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.
