There are taxi ranks outside Bristol and Nottingham stations with
'London' taxis queuing up at both on Google Streetview. Blue and green
rather than black.

Ironically the first thing I saw on nottingham streetview outside the station
is a prius taxi.

That's a minicab - no "Taxi" sign on the roof. Duh.

There do seem to be some TXs there,

Like these ten you mean? https://goo.gl/maps/Uwr3kWQE4hk

And another dozen inside, he https://goo.gl/maps/no195yz2Ze72
to he https://goo.gl/maps/bep6nJZHu6R2

but a quick random sample around the rest of the city doesn't show any

Other than the dozen lined up here... https://goo.gl/maps/dXRA1p1rBAM2

and... oh I can't be bothered. You get the drift.

so they can't be that common. I can't imagine why they use them there.

Imagination is not your strong suit.
