So I remember about 15 years ago there was a campaign to save the cheque. Cheques were duly saved but you try using one now.
This has just delayed things by about 5 years
There are perhaps two points:
1 - Yes, it was premature to attempt to remove ticket offices when ticketing is still a minefield and work is underway to improve ticketing options, smartcards, contactless etc - there's LOADS more work and investment needed for that.
2 - Ticket offices weren't saved just because people complained that they wanted to buy tickets from a real person, it was because they're a known source of information and assistance rather than searching around the station for someone in a hi-vis that may or may not be able to help you (is it platform staff, is it revenue, is it a driver, is it Network Rail, is it some random worker for another company in an orange hi-vis...). Disabled groups rightly focussed on that, and that will still be true in five years, ten years, fifteen.. at least as long as we want to make rail travel truly accessible*.
* Or we rebuild all platforms and introduce rolling stock with level access everywhere... a great aspiration, but the industry is trying to save money.
