Hessa Tor opens the road crew’s stonefall notices and the mule train delay book at the west switchback above the mule rest. Before anyone moves a cart or changes a mark, the crew checks a fresh fan of chips below the retaining wall’s third drain. The thaw season air brings its own pace to the passage.

The latest page holds 62 switchback closures lasting longer than one bell. Hessa Tor reads the previous count (58) before the next mark is made. It is a small pause, long enough for the people at the rail to hear what the number leaves out.

Carriers call short closures manageable; masons say repeated traffic shakes loose stone from the same seam. The current record does not settle that disagreement. The difference between those accounts is visible here: a rule on the board and a working condition just beyond it.

A second set of hands has checked the count and recorded where the methods differ. The entry belongs to the winter count file at the west switchback above the mule rest. The next check will be made by another crew, asked to repeat the measure without borrowing the first crew’s conclusion.

When the shift closes, the file remains beside the marked place. The route marshal will time a loaded test after the drain has been cleared. Until then, the route, schedule or allotment stays as it was at the opening bell.
