Chapter 49: Placards and the shop
Twenty yards of placards and the shop
Placarded hazmat cars may not couple directly to the engine, may not be humped and may not be kicked, so they have to travel with a buffer car between them and the power.
Cars carry cards: a bad-order car must stand on the RIP track, a load must cross the scale, a reefer must stop at the icing platform, before it counts at its destination.
20 yards, pars from 7 to 16 moves. Beside its theme, chapter 49 draws on timetables, hidden waybills and the hump, with two breathers of plain sorting and extra cars. Difficulty runs as a sawtooth: runs of easy yards, a spike, a breather.
