Escalators on the Munich public transport network
There is an unwritten rule concerning the use of escalators on the Munich public transport system. If you are standing still, stick to the right and allow others to pass on the left. Something to do with driving on the wrong side of the road I guess!
Actually, it's not entirely unwritten. Some escalators actually have little pictograms illustrating this point. They are conveniently located close to the floor so you are only likely to spot them if you are scanning the output of your ankle mounted webcam. That's just as well really as some of the pictograms contradict this rule and that would only confuse you as throughout the system "rechts stehen, links gehen" is the habit.
That's it and you will now know what is going on if you get shouted at. Actually, it could be worse than a shout. If somebody is in a hurry and he knows that the rule is backed up by signs on your escalator, he may just feel entitled to administer a hefty shove to clear the way.
There is something else to consider.
You are not so stupid as to try to take a full luggage trolly on the escalator but plenty of others are. Usually, what happens is that about half way down, the whole lot falls over leaving a heap of bodies, cases and a trolly heading to whatever fate holds in store at the end of the line.
It's not so bad as in the movies where the hero is trussed up on the conveyor belt heading for the buzz saw or the chicken pie machine but it's not a lot of fun.
It's also not a lot of fun for the folks travelling behind because fate is about to dump them atop this writhing pile.
You won't be able to reach the emergency stop switches and German nature is to watch events unfold and not to interfere with kismet.
I see this happen about once a year and I will not get on an escalator in Munich without have at least a quick glance at what else is on there.
