One of the things that is good to know before getting on the London Underground is that if you use escalators there is a rule: Stand on the right.
This is done so that there is always a fast lane on the left side, thus forming a line of people who are standing still on the right and leaving a gap on the left for those who are in a hurry and want to walk up or down the stairs. do it without hindrance.
It’s a well-known rule for Londoners, so you know, stand in line to the right, that if you can’t get run over, especially if it’s central London at rush hour!
