Just out of interest, how/on what basis are fares currently calculated? What factors are taking into account?
(I fully appreciate that a comprehensive answer would probably dwarf the Iliad!)
Whilst I was busy rattling away on my keyboard I see that Graham has beaten me to it with part of the answer. But as I've been typing out War & Peace I'll post it anyway
Being old enough to remember when a flat rate pence per mile system operated throughout the
BR▸ rail network, I recall that the original idea was described as Market Pricing ie. Charging what the market would bear. But even then before that was introduced (c.1964
IIRC▸ ) there were anomalies with discounted tickets, one of which was described in Gerry Fiennes’ books when he got a complaint about it. That was a day return from Oxford to Banbury costing 7s/6d whilst a day return in the opposite direction cost 7s/9d. Quite simply, more people in Banbury wanted daytrips to Oxford than people in Oxford wanted day trips to Banbury, so the railway charged more to the Oxford-bound day trippers.
Another initiative introduced in the 1960s was intended (once again IIRC) to stagger weekend holiday peaks by offering a mid-week return between any two stations in the
UK▸ , allowing outward travel TWThO in one week, and TWThO return travel the next week, at about two-thirds of the ordinary return fare. These tickets were withdrawn when it dawned on BR that people who went to the same location week in week out could buy another mid week return going the other way and get a third off their regular fare prices.
So it is and so it will always be. Whenever, for example, HMRC come up with a new rule to plug a tax loophole, some smart Alec somewhere will think of a workaround. Rail fares are no different in principle.
On reading some of the posts in this thread I get the impression that some poster might not, perhaps, have fully thought through what they are saying or suggesting. “If you buy more of something you expect it at a cheaper price” for example – try not changing your insurance company for 10 years and then see how much more you are paying than a new customer. And you will come across plenty of examples in supermarkets where a discounted item (say normally £1.50 reduced to £1.00) makes it cheaper to buy two of those than the larger box with twice as much product that is still selling for its RRP of £2.50.
I also read “The more 'mainstream' split ticketing becomes the more the
RDG‡ will look to close it down.” And how are they going to do that, pray tell? To take Graham’s example of an anytime
BRI» PAD» costing £224.20 whilst splitting at
DID» costs £137.30, a saving of £87.10. Now, “they” could say that you have to leave the station and come back in again to get the second half of your split validated and, whilst that would certainly put an obstacle in the way of splitting, I doubt that I am alone in being quite happy to wait half an hour or so at DID for the next train. But how would it go down with each party? The
TOC▸ wouldn’t like it because it didn’t increase their revenue, the passenger wouldn’t like it because it pointlessly increased their journey times, and the only people that would be happy would be those who sell tea and coffee on DID station (akin to the Swindon refreshment break if old, perhaps...)
And when I think about it, there are many pitfalls in going back to the flat rate per mile too. There are 118 miles between Bristol and Paddington. It is also 118 miles from Llangammarch to Uttoxeter, or from Severn Tunnel Junction to Fratton, or from Southport to Poppleton. Are you sure the market would bear exactly the same price for all of them? I’m not...
And I'm also glad I'm not called Keith Williams...
