Chapter 147: Timetables and stub tracks
Twenty yards of timetables and stub tracks
The move counter is a clock. Arrivals roll in off the main at their move and need room; departures leave on time only if the train is standing in order, or the shift is lost.
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 6 to 19 moves. Beside its theme, chapter 147 draws on repair time, outbounds and tonnage, with two breathers of plain sorting and extra cars. Difficulty runs as a sawtooth: runs of easy yards, a spike, a breather.
