250m long? That'll produce some interesting bunching of passengers down
one end. I doubt many people will spend 3 minutes walking down the length
of the platform.

Why should it? The central underground stations are double ended, (eg
Farringdon/Barbican, Moorgate/Liverpool St) with access to the platforms

Unless the entrances are spaced a reasonable distance apart then passengers
are going to have to walk those 250 metres at some point , whether its on
the platform or in a connecting tunnel.
