What I find a bit worrying is that the restriction wordings can be changed at any time, and there is no audit trail of when they were changed. So I can buy a ticket on one day, relying on the then current wording, and find that by the time I have travelled the restriction means that my ticket is no longer valid.
I would be pretty sure that if you purchased a ticket for travel at a later date, based on reading conditions which tell you it is valid on the train you intend to take, and the condition is subsequently changed, then you have every legal right to travel on the train with that ticket as the conditions were when you bought it. A poor show for any company to sell you a product, take your money, then change the spec before you get the product or service in such a way that it's no longer what you require. I suspect, however, that there are very few super off peak Castle Cary to London tickets already purchased for the 09:42 with people still to use them.
The grey area (if you like to call it that) is for people who - like our member here, I believe, have researched and decided to buy a product - and one that was stated to be available until and including Friday 13th December. But then to find (or not find until they get stopped on the day) that the product was changed, after they researched it for their chosen day but before they actually bought the ticket, in such a way it was no longer suitable for them. Legally, I suspect the
TOC▸ can change the conditions for new sales at any time, though I suspect that there may be franchise and other contractual elements in place to stop them changing fares of which trains are in which fare brackets without notice.
Unless I took a print out of the previous wording (which let's face it most people won't do), there's no evidence to disprove the railway company's version of events.
Indeed - though I don't think there's anyone from
GWR▸ who's argued in the current case that the super off peak fare start time from Castle Cary was never before the 09:42 departure; in any case, we do have evidence here on the forum in this case.
I do find it surprising that the fare condition was changed mid-timetable to correct what I suspect was an unintended loophole that had been created for super off peak tickets to be used from one particular station. Yes, of course errors will come to light and need to be corrected, but for GWR to do so out of the normal cycle of fare updates, without (as far as I know) notice to or consultation with anyone ... and for an error which will flush out of the system on 16th December and become irrelevant anyway, seems churlish and likely to cost them more in customer relations than they'll gain in extra revenue. I wonder why they simply didn't leave it alone for the next few weeks, when the issue goes away.
