Kip Moss opens signal patterns, maintenance cards and changes submitted by route crews at the signal board at Three Roots Junction. Before anyone changes a mark, the crew checks two adjacent branches use a different pause after the second knock. The deep rest period sets the pace of the work.
The page holds 22 signals with a dated source and a matching branch label. Kip Moss reads the preceding count, 25, before the next line is entered. A number without a date would not tell the next crew what changed.
The registry follows the written pattern. Route crews say an echo changes how the pause is heard at the junction. Here the difference is visible between the posted rule and the route, service or shift just beyond the door.
Afield walk checks the route from entry point to final branch. The Year third, deep rest window 2 file remains open for its scheduled decision. The keeper will test both signals from the approach path and the branch interior.
The shift closes with the source page attached to the board. The next file uses a new date and scope.
