So how do you know which is which?

If it's like Brussels or Cologne, there's a blue circular "Ahead Only"
traffic-type sign on one escalator and a red circular "No Entry" sign on
the other.

Many countries have escalators that work "on demand" and usage is on a
combination of signage and context. It's common to have an "up"
escalator but only "down" stairs, or there's an obvious tidal flow that
the escalator is servicing (eg 'towards' baggage claim at an airport).

Most (all?) of the ones on the Munich S/U-Bahn seem to work on a "who steps
on the actuator plate first" system. As you approach your stopped escalator
(with an illuminated sign showing two arrows pointing up and down) and step
onto the flat plate at the start, the escalator bursts into life, the double
arrow light at the start end changes to a single arrow pointing in the
direction of travel and the double arrow at the terminus end changes to a
"No Entry" type roundel. The escalator keeps going for as long as people
keep stepping on the actuator plate, then after it has moved sufficient
distance to transport the last person to step on the actuator to the other
end, it runs for about another 5 seconds then stops and goes back into
"first-come" mode. Of course, for the impartial observer, this provides for
some most amusing spectating of "can I get to the actuator before that
bugger coming the other way" type racing.

So if two people approach two escalators from the top, both escalators start
running down, and then a trainfull of people arrive at the bottom with no up
escalator for them?

From what I can remember (most of my jaunts around Munich have involved
pub-crawls, so details are sometimes a bit hazy) if there is more than one
flight of escalators in a stairwell there is a dedicated "up" one and a
dedicated "down" one. The two way ones seem to be where there is only one
escalator in a stairwell. Most stations that I have used have multiple
entrance/exits that only get one escalator each, however the main entrances
to busy stations in the middle of town often have 4 escalators (2 up, 2
down) available. These still go to sleep when no-one is using them but the
light up signs indicating DOT remain illuminated so you know which actuator
plate to step on.

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!

I believe it, but what possible use could that be? Unless there was
some control, you'd end up with everything going the same way and no
way either in or out depending on chance.

Why should an one person set the direction of the whole escalator by
chance? An intelligent decision about how many escalators need to go
each way at a particular time of day is far more appropriate.
