There seems to be an argument in this and other posts that the ticket condition which allows ending a journey early and break of journey means that the train company has offered the ticket A to C for sale to make a journey from A to B such that there is effectively 2 different tickets for sale for the journey A to B – you can either buy a ticket A to B or buy a ticket A to C, both are valid for the journey A to B. I don’t believe this to be the case, but I’ve been unable to obtain a definitive answer from anyone.
I believe that it is absolutely clear and unequivocal that an A to C ticket which allows BoJ is indeed valid to make a journey from A to intermediate station B regardless of the pricing of the A to B ticket. To argue otherwise would be to claim that a ticket condition (and therefore contractual term) which clearly and unequivocally permits BoJ at intermediate stations does not actually permit BoJ after all; such an interpretation would be absurd, perverse, and turn the meaning of the English language on its head.
The TOCs might not wish this to be the case, and might even publicly claim that it is not the case, but they are nonetheless bound by the conditions of their franchise agreements and the wholly clear wording of the NRCoC.
Furthermore, if a TOC falsely claims that an A to C ticket which permits BoJ is not valid for travel to intermediate station B, then it is the TOC that has committed a crime, namely, a misleading commercial practice contrary to the Consumer Protection from Unfair Trading Regulations 2008, and, if it does so knowing of the falsity of the statement in order to cynically maximise profit, then it is the TOC which has made a fraudulent misrepresentation.
"Discussions with the TOC" are not necessary or helpful in determining the validity of the ticket, especially as the TOC has a clear financial incentive to make a fraudulent misrepresentation; the wording of the contract is what matters, and, as I understand it, at least two prosecutions for using Condition 19 splits to save money on the advertised through fare have already failed after the magistrates accepted that it is fare avoidance rather than fare evasion and that fare avoidance is wholly legitimate.
In the days of rovers, rangers, season tickets, advance tickets (with multiple prices for the same journey), Megatrain tickets, combinations of tickets, anytime tickets, and off-peak tickets there is no longer only one valid fare between stations A to B, but rather several valid fares between any given pair of stations.
Having freely entered into a contract for travel which allows BoJ at intermediate stations, the TOC(s) cannot evade their obligations simply because they regret the bargain they have entered into, any more than a passenger who buys a ticket and no longer needs to travel is entitled to demand a full refund because he or she regrets the bargain he or she has entered into.
Fare avoidance, like tax avoidance, (and unlike tax evasion and fare evasion) is wholly legitimate, and most certainly does not constitute a fraud.
A passenger who buys an A to C ticket online, or who simply requests to purchase an A to C ticket, which permits BoJ, without expanding on that statement, does not make any representation about the actual journey they intend to make, (and silence does not constitute a misrepresentation). In the specific case of a season ticket, a person buying an A to C season ticket intending to travel primarily from A to B may nonetheless wish to travel to C on occasion.
If a passenger buys an A to C ticket which permits BoJ, then the only conditions and prices that matter are those of the contract which has actually been entered into, namely those associated with the A to C ticket. The conditions and pricing of a A to B ticket is not at all relevant because the passenger has not entered into that contract.
To those who claim it is not valid, I would ask:
1) Do you accept that tickets which clearly permit BoJ do indeed, by virtue of the plain and clear wording of NRCoC Condition 16, allow travel to intermediate stations at the passenger's sole discretion, acknowledge that this Condition cannot be interpreted in any other way, and futher accept that that the passenger's reasoning for making that journey cannot logically or reasonably amount to a secret condition overriding the contractual condition allowing BoJ?
2) If you claim that an A to C season ticket must be used primarly between stations A and C only, what is the precise proportion of journeys for which you claim that BoJ at intermediate stations is secretly forbidden (without the passenger even being informed of this secret condition), or do you claim that BoJ at intermediate stations is not allowed at all?
3) Do you (or would you) practice tax avoidance by putting money in ISAs; if so, do you accept that tax avoidance is legitimate, and, if so, do you accept that fare avoidance, as distinct from fare evasion, is also legitimate? If not, why not?
4) If a passenger has purchased an A to C ticket, why exactly are the conditions and pricings of an A to B ticket of any relevance at all to the interpretation and terms of the A to C ticket, since buying the A to B ticket would constitute a separate contract, and one which the passenger has not actually entered into?
5) Would you claim that a passenger who buys a rover in order to save money on a point-to-point SVR ticket has committed a fraud, and, if not, how does this differ from a passenger who buys a season ticket (effectively a point-to-point rover) or an ordinary ticket in order to save money?
