I see the BBC now mention this though only relating to Southern stations.

Ticket offices across the Southern rail network could close or have their hours cuts under plans to modernise, the operator has said.
Govia Thameslink Railway (GTR), which runs Southern and Gatwick Express, said more passengers were buying tickets online or using smartcard technology.
The Campaign for Better Transport said people needed ticket offices because of the complex ticketing system.
The plans affect 51 stations in London, Sussex and Surrey.
Under the proposals, ticket office staff will be moved on to the concourse to be "station hosts" who can sell tickets.
Some station ticket windows will close and others will only be staffed at peak times.
A GTR spokesman said: "Where sales from a ticket office are low, we will bring staff out from the ticket office on to the concourse as station hosts, where they will be readily available to help with ticket purchasing and offer assistance to passengers."
He said all affected stations would be staffed for longer.
Similar plans on the London Underground led to a prolonged industrial dispute.
Steven Joseph, from the Campaign for Better Transport, said: "It's one thing to do this on the London Underground where the fare structure is relatively simple and London Underground have done that in London.
"It's another thing to do it when you've got this incredibly complex fare structure.
"It depends on how it works out in practice, I think we'll want to see what happens."
Southern said no ticket offices would close immediately and proposals would go through consultation, be discussed with London TravelWatch and Transport Focus and require approval from the Department for Transport.
The rail firm said it was talking to trade unions and there would be no compulsory redundancies.
The company runs rail services between London and the south coast, through Sussex, Surrey and parts of Kent and Hampshire.
