Why do train staff point at things and call out even when nobody's around?
Conductors and platform staff point at signals, mirrors, and the gap between the platform and train while calling out “check.” This practice is known as shisa kanko, or pointing and calling.
It is a method for becoming clearly conscious of what has been checked. Pointing and speaking aloud focuses attention and reduces checking errors.
Why — five layers
Railway companies adopted it as a safety-checking procedure, and crew and staff learn it in training. The action is not performed for show but to make certain that the person has completed the check.
Following the prescribed form is emphasized. When everyone performs the same action, it helps prevent checks from being missed.
Pointing and calling is a safety-checking method shared throughout the workplace. When everyone performs the same action, people nearby can also understand the status of the check.
International view
Pointing and calling originated and developed as a safety-checking method on Japanese railways. Today, railways overseas can also be seen adopting practices modeled on the Japanese method.
But not always
Station staff and train crew who are pointing and calling are carrying out a safety check. If you need to speak to them, wait until they have finished.
What to do
Nothing to do, just know it's a deliberate safety check, not the person talking to themselves or to you.
