True , but I was thinking of it being a way of clearing out the rush

The most dangerous thing is to move the crush to the top of the
escalator. The throughput of the escalator must not exceed the
throughput of the ticket barriers or you get Hillsbourgh in a tube
station. People cannot wait on escalators if there is a crowd ahead,
but they can wait at the base where nothing is forcing them forward.

On the other hand, when the crush _that_ bad, then yes, stand on both
sides as long as the barriers at the top can handle it. However, it
signifies that something needs to be done, usually involving adding an
extra escalator. And that's expensive.
