What is the etiquette for standing on escalators in London's tube stations?

In London's tube stations, it is generally expected that if you are standing on the escalator, you should stand on the right-hand side, leaving the left-hand side clear for people who want to walk up or down the escalator. This is especially important during peak travel times when stations can become crowded. If you choose to walk up or down the escalator, you should do so on the left-hand side.

It is worth noting that this etiquette may not be followed in all tube stations or in other countries, so it is important to pay attention to the behavior of those around you and follow local customs. Additionally, it is important to be aware of safety guidelines, such as holding onto the handrail while on the escalator and avoiding loose clothing or items that could get caught in the escalator mechanism.
