Anyhow I was initially stopped at Kings X because I have a super off peak ticket, which the chap said was only valid after 7pm.
But then he spoke with his supervisor and said it was all OK.
He said something about network areas being right next to each other, which I completely did not understand.
I checked with the train guard before boarding and he was happy for me to travel.
Yes, I'm aware of several instances of gateline staff at King's Cross and Paddington falsely claiming that valid tickets are not valid. I am glad to hear the supervisor was well trained; well done VTEC! Sadly not all supervisors are even prepared to look at the rules. I had the misfortune to encounter one at King's Cross who denied
Hadders travel and refused to even look up the restriction code applicable to the ticket held. I won't easily forget the nonsense that he made up about how gatelines work!
However the vast majority of VTEC/GWR Train Managers are appropriately trained and instances of TMs denying valid tickets are valid are quite rare. There is one whose name kept cropping up for wrongly charging people (e.g. denying that a via Peterborough fare was valid via Peterborough and denying that a combination of fares can be used for one journey) but I've not heard of any recent incidents, thankfully.
I wouldn't worry too much. If anyone questions it, simply show them your reservations and/or itinerary produced by the website.
If you are ever charged an excess fare (this would be the difference between Super Off Peak and either Off Peak or Anytime, as deemed 'appropriate') you would be able to get this refunded from whichever company wrongly charged you. If that ever does happen, make sure you contact us for advice. If you travel in accordance with an itinerary I can pretty much guarantee you will get your money back.
