Chapter 153: No-engine tracks and auto racks
Twenty yards of no-engine tracks and auto racks
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.
An auto rack is two car lengths long and takes two slots on a track and two behind the engine, so every capacity becomes a length budget.
20 yards, pars from 4 to 13 moves. Beside its theme, chapter 153 draws on the helper, placard spacing and placards, with two breathers of plain sorting and extra cars. Difficulty runs as a sawtooth: runs of easy yards, a spike, a breather.
