Public-board attention notice
Representative transit hall practice, 1960–2000
Observed surface
When the mechanism begins, look up before moving toward the platform.
Read the complete row after the sound stops; intermediate letters are mechanical travel, not information.
Confirm destination, time, and status together.
Implied procedure
Do not treat a quiet board as a current board. Silence means only that no update is physically underway.
If several rows turn at once, allow the full cascade to finish before acting on a partial change.
Interpretive residue
The notice describes a display with two publics: those close enough to read it and everyone close enough to hear it.
Sound announced that information was changing before it announced what the new information was.
