Because it alerts the customer at the point of that Railcard Check or Survey Check that their Railcard whilst valid then, will not be in 3 days or 5 days or suchlike which prompts a renewal thus preventing issues in a weeks time if they were previously unaware of the cards upcoming expiry.
We also frequently come across holders of 16-25 railcards having purchased tickets with the 16-17 Saver card 50% of which their Railcard only entities them to the 33.33333% discount thus obtaining a greater discount to which they are not entitled.
Although if genuinely aged 16 or 17 it would be simpler to make the 16-25 railcard an 18-25 card and sell the 16-17 saver cards to those aged 16/17 giving them the 50% discount anyway and saving this 2 level discount for that age group!!
Is the 16-25 one of the regulated railcards which can't be withdrawn, alongside the disabled and senior ones?
Yes, in an ideal world the various discount product sets could be sorted to remove overlaps but the various bits of regulation and the lack of an overall authority in charge makes this implausibly impossible with the current structure. GBR, once legally established, will be in a much better place to sort it out.
Indeed, or the Government could simply lean on the RDG to change the terms of Railcards so that they provided no useful discount whatsoever, or were withdrawn altogether.
This section was, if I'm not mistaken, an amendment to the original Bill proposed by backbechers to protect 'vulnerable' people from unrestrained market forces under the newly privatised TOCs. It clearly did not envision the possibility of such changes being made on account of the government bearing the revenue risk.
Government does not 'lean on' RDG. Until legislation can change the current structure, RDG is legally answerable to its members; they, however are contractors to DfT/Wales/Scotland or the devolved regional bodies as appropriate. So the DfT instructs RDG via its TOC contracts and the other authorities can do likewise.
Railcards are highly unlikely to be withdrawn.
A 50% increase in fares is hardly going to go down well during a cost of living crisis.
Indeed. Whitehall is a hotbed of competing political fiefdoms and whilst Treasury might like to rein in rail spending, the DfT, No.10, loads of MPs in marginal constituencies and the devolved nations and regions mean that there is no chance of that happening. A more rational debate is about improving the reach of discounts to those that need them and those that drive modal shift.
