Many countries have escalators that work "on demand" and usage is on a
combination of signage and context.

Including Hamburg, where my old local station, Kiwittsmoor, had one
escalator which was up in the morning and down in the evening, as I
recall.

I'm pretty sure I've also encountered ones that will go either way
depending who gets there first!
