Only for the people who stand, not for the people who walk, because the people who stand and queue up leave passage for the people who walk to pass through.
I can't comment on arbitrary metro systems around the world, but where I live this always happens. When demand is high, people who stand queue up for the escalator, but there is always enough space for people who walk such they are unimpeded.
Very rarely demand is so high that people queue up for the trains themselves (only saw this twice in my life, I think), but even then, there isn't any congestion on the stairs.
- notacoward 10y agoIn my experience - many systems all over the world, though none as a regular commute since 1995 - the clot of people queuing to stand often severely impacts ability to reach the walking side. An even bigger impact is people who aren't good about standing all the way to the right, impeding progress for the walkers on the left. This phenomenon seems to get worse as queues get longer, though that might not be the case in London with its notoriously strong social norms. In both cases, though, a lack of sufficient throughput does impede walkers as well.
