I've just thought of something else that would count against an average fare based on a pence per mile fare structure.
The average that I calculated for Swindon to Birmingham by the various routes was £76.90, rather more than the £52.80 for the shortest route.
If there was no average fare that needed to be calculated because there is obviously only one route to take eg. Swindon to Stroud, Stroud to Cheltenham and Cheltenham to Brum, a savvy traveller could save £24.10 by - wait for it - splitting the ticket Grin
My point remains, and is confirmed - it's meant to be a public transport service, not an initiative test.
Whilst I agree with you in principle, it is when we get down into the details that the problems become apparent. It is easy to say "there should be one fare irrespective of routeing," and when we are talking simple no-argument journeys such as Melksham to Chippenham or Stroud to Kemble then of course it can be done (and is generally being done now of course in terms of one fare for a particular type of ticket).
But as I showed in that little bit of research this could then throw up a new set of quirks and idiosyncrasies elsewhere. On an apparently simple journey from Swindon to Birmingham where there is normally no through service and multiple routes, how do you:
Set a one-size-fits-all fare that is fair to both the passengers and the
TOCs▸ ?
Make sure that you do not create new anomalies for others making broadly similar journeys?
Make sure that this one-size-fits-all fare does not make it possible for others to get a cheaper fare than they "ought" to be paying?
What happened to me this morning encapsulates the issue for me. I looked at some possible options for doing things differently to how they are done now and posted that research, with comments. I then went off to make a cup of coffee whilst still thinking about it and a new loophole suddenly sprang to mind.
As I said only a few days ago on this forum (but a different thread
IIRC▸ ) there are similarities here with HMRC and accountants finding new loopholes after HMRC ave just closed the old ones. I found a new loophole that would have blown one of my options out of the water if it had been one recommended in the review, after about 5 minutes further thought. And it would have involved the reintroduction of split ticketing that the railway and passengers in general appear to want to see stopped.
We have only been looking at Swindon to Birmingham, but there are potentially thousands of examples all around the
UK▸ . And each one of those examples would have to have a fare set in such a way that no loopholes existed, no new anomalies arose, and the prices charged represented a fair return to the TOCs who were charged with providing the services on which that ticket would be used.
Brexit is a piece of cake by comparison
