people don't "look" disabled, but still find stairs difficult
or impossible.

There's also the halfway house of the many stations that have escalators
rather than lifts: not very much use to wheelchair users, but very helpful
to many other travellers who may have trouble with stairs, particularly
when carrying luggage.

Mindful that many stations with escalators (or indeed original lifts)
aren't completely step-free, typically having a short flight of steps
adjacent to the platform, and often a flight of steps to get from the
ticket concourse to the roadway outside.

Yes, usually caused by the fact that both lines had to be fitted under
the roadway, leaving inadequate space for lifts or escalators between
the lines, so the landings had to be above rather than between the
platform tunnels. Less of a problem with new or rebuilt stations.

But my point remains: as Boltar asserts in his inimitable way, there
are few actual or even potential Tube pax who are completely confined
to wheelchairs, but a much larger number who have limited mobility or
are hauling luggage, pushchairs, etc. They can probably manage short
staircases and escalators, but struggle with long staircases.
