With Japanese trains I understand that not only the station staff but also the drivers point and call, sometimes even when no one is around to hear them, as a means of reinforcing their behaviour in regard to important safety procedures. This could be regarded as talking to oneself for public safety reasons!

Pointing and calling is a method in occupational safety for avoiding mistakes by pointing at important indicators and verbally calling out their status. It is especially common on Japanese railways, where it is referred to as shisa kanko (指差喚呼), shisa kakunin kanko (指差確認喚呼) or yubisashi koshō (指差呼称); in Mainland Chinese and Taiwanese railways, where it is called 指差呼唤; 指差確認 (zhǐchā hūhuàn); and in Indonesian railways, where it is known as tunjuk-sebut. Gesturing at and verbalizing these indicators helps with focus.
