Those are taxis licensed to wait/ply for hire on the station forecourt.
Indeed - and ARE there typically taxis waiting / plying for business at Kemble station?
Please follow up, members - are taxis generally waiting / plying for hire at your local station? If not, how easy is it to get a taxi and is there a single source / booking mechanism you would use (be it a local co-operative or something like Uber) or would you be searching / calling lots of different numbers?
This sounds like a job for a poll or two. I seldom take them, visually, there's plenty at Bath Spa during the day, rather less availability into the evenings and often a wait for taxis later in the evening when the city's bus service has also fizzled.
Anecdotally, advance-booking a taxi in Bath to e.g. the railway station for a train, is a risk as, once it's booked, the taxi booking system holds the job until the appropriate time and then chucks it into the pool in the hope that a driver is available to pick it up.
Also, booking via an app is encouraged and the last time I tried a phone booking the thing went to dev/null.
(I may have this completely wrong as to how the industry now works, but taxi drivers seem to be struggling with it too...)
Also, a significant taxi-travel requirement is for accessible vehicles and I'm not sure how this is met now.
