Not entirely relevant, but I have been quite surprised today by a request to passengers who use split tickets to provide *all* tickets they are using for the current journey, and not only the one relevant to the segment they were on. Is this a new practice?
Recently on GWR mainline services (mostly Bristol-London, either route) this practice seems to have gone from almost never to sporadic.
It creates a theoretical paradox for me as I do multiple manual splitting wherever possible and journeys on this particular route go through phases of being ridiculously unreliable. So, I only buy tickets when approaching the station where validity of my current ticket along my current route ends. Doubly so with the impending changes to refund rules adding even more friction to dealing with things going wrong - which happens wearyingly often.
At the point of inspection I therefore maintain the belief that my intended journey is to the destination my current ticket states. That'll usually be to a station I never travel to so by definition won't be the split point I'm subsequently spontaneously inspired to use.
I then have a sudden inspiration to travel to another station I never go to either just far enough in advance of reaching the relevant split point to buy the next ticket.
It's also wise to maintain this indecisiveness so as to not draw to the inspectors' attention that you're using a middle bit of validity of some other ticket rather than a ticket expressly between your current origin and destination as it's cheaper but still 100% valid. Doubly so when it's RPIs. I'm pretty confident that someone spotting these in the wild has previously led to information being fed up the chain to someone who then tries to find a way to hobble the opportunity to keep using those tickets in this way.
When, very occasionally, an inspector notices I'm still on a train which is inconsistent with their memory of where I'd previously decided I was going and they can be bothered (fortunately a very tiny bit of a Venn diagram) I find that channeling Sir Humphrey Appleby at his most convoluted is the way to make them lose the will.
As far as I can tell, such chronic indecisiveness leaves you still 100% within the rules as (ambiguously) drafted while remaining consistent with having more sense than money.
Given the current trajectory, maybe it's only a matter of time before the enforcement apparatus finds a way to start punishing thought crimes...
