Gaps in the shift notes: what never gets written

Radio calls, clock changes after maintenance, and the ten minutes of load on the wrong bus are the lines that vanish from a logbook written at dawn.

Dawn logbooks are calmer than the night they describe. That calm is a kindness to the next shift. It is also a filter. The lines that vanish are usually the ones a reconstruction needs.

Clock changes

After maintenance a panel clock is often set “close enough.” Nobody writes it down because the feeder is back. Weeks later a trip makes that minute famous. The maintenance sheet is the right place for the note, the same day, not during an inquiry.

Radio and telephone orders

A switching order given on the radio may never enter the log if the writer was also the person climbing the stairs. We ask for radio notes, even scraps. If none exist we label the oral account as memory and we do not promote it to a timestamp.

Load on the wrong bus

Ten minutes of load picked up on a bus that was not the intended one is embarrassing and therefore under-described. It is also the kind of fact a neighbouring operator will notice from their own traces. Write the ten minutes. The briefing will be shorter for it.

Silent hours

A log that jumps from 03:20 to 04:10 is a document. Do not fill it later with a smoother hand unless you mark the copy as a copy. We would rather have a gap than a page that pretends to have been written in the dark.
