Escalator etiquette on the underground platforms
Launch library · evergreen read

On the busier underground platforms, an unwritten rule keeps one side of the escalator clear for anyone in a hurry, a habit locals maintain instinctively even when the platform is otherwise nearly empty. Tourists unfamiliar with the convention sometimes need only one mildly awkward moment before they adjust their stance for the rest of the trip.
Standing on the wrong side during peak hour draws little more than a mildly pointed glance, but it is enough to make most people shuffle across quickly, keen to avoid becoming a minor obstacle in someone else's rushed commute. Even during quieter stretches of the day, most commuters maintain the habit purely out of ingrained routine rather than genuine necessity.
Visitors unfamiliar with the convention sometimes cause a small, temporary bottleneck without realising it, a gentle reminder of just how much of daily commuting etiquette here runs on habits nobody actually explains out loud. Locals rarely comment on the rule directly, treating it as such an obvious expectation that explaining it feels almost unnecessary.
