I dont always receive the email for some reason. I've tried it on 2 different accounts and sometimes I get the email, sometimes I don't. Not sure if it's a problem at Northern's end or mine.
I always get the payment confirmation email though, is there a specific reason Northern don't just send them in the same email?
I'm the same, prefer the paper ticket. Only annoying bit of the paper tickets is I can't take advantage on Northern's on the day advanced ticket prices when buying at a ticket office. £9.90 advanced vs £37 walk up for OMS to YRK. Give ticket offices the chance to sell on the day advanced ticket prices and I will be happy to stand in the queue (assuming I don't miss the train).
It's worth noting that you could buy tickets from another retailer if you're having trouble getting the emails. Many retailers will sell you tickets fee-free (all of the TOCs, plus several third party retailers) - the question is what additional benefit they're offering you. For instance, some retailers offer fee-free refunds (obviously not for Advance tickets) or changes.
It might have been discussed already, but do TOCs dictate a reasonable time to arrive at a station before departure with consideration to time spent in queues?
When BR was forced to introduce a Passenger's Charter in the early 90s (as part of John Major's drive to introduce Charters across the public sector), it included a section on queuing time. Penalty Fares were first introduced around the same time; one of the key measures that various Parliamentarians insisted on as a safeguard against the newly reversed burden of proof was that you couldn't be penalised if the queue exceeded this duration, or at least you could quickly and easily obtain a Permit to Travel from a separate machine.
This protection was essentially kept under the post-privatisation Strategic Rail Authority's Penalty Fares Rules, but with the introduction of the new Penalty Fares Regulations in 2018, all that was removed.
Though some TOCs still put down "aims" for queue times in their Charters, many don't bother anymore. Certainly none say that you can buy on board because of a long queue, and the facility to obtain a Permit to Travel has been removed from most stations. Northern introduced their own Promise to Pay Notice scheme, but this is only available from a ticket machine - the queue for which you may be waiting in!
Or is just a hard line of "tough, you should have turned up earlier, but we're not going to tell you how much earlier".
That is the nonsensical position the industry currently maintains, yes.
