Aside from (as already mentioned) this being incorrect action to excess an expired Advance ticket as it should have been discarded and the passenger requested to buy a brand new ticket
As long as I meet as a base standard that the NRCoT and the conditions of ticket issue provide, and I don't ever do anything which contravenes the rights of the passenger ,- on my train the correct action is the one that's in the best interests of customer service. It's an authority that I have as a train guard - and one I use wisely.
, I was under the impression that it isn't permitted to excess a TOC specific ticket (or on this case I'm assuming it's LNER & Connections) to an Any Permitted fare.
You are absolutely correct. You may excess a TOC only ticket to another type : say off peak to anytime, or single to return. You can't excess away the TOC restriction to any permitted.
Your comment seems to imply that you think that an Advance ticket is a TOC - restricted ticket. I know that you cannot possibly have meant to imply this, however. We know that an Advance ticket is a service-specific ticket, and you can excess such tickets to any permitted at will.
In any event, in the example I quoted, there was no change of TOC, just a change of validity.
I do wonder sometimes how much revenue training some TOC Conductors get.
I really hope that wasn't aimed at me.
I agree, the training given to conductors is poor. Knowledge is also shrinking as conductors retail fewer tickets, and therefore are exposed less to unusual and niche ticketing oddities . That notwithstanding, I'm confident that I can hold my own against the best.
