My non-expert opinion is that, if an A to C ticket which freely permits BoJ is used to travel to intermediate station B (where B is an intermediate station *only* by virtual of the "through train" rule) and to finish "short" without ever resuming, then the actual journey made is A to B.
This is notwithstanding that routeings (including the determination of through trains and permitted routes) are of course determined by the A to C ticket, on the assumption that the passenger is actually travelling from A to C.
In this case, the journey to the intermediate station "B" is made on a single train, and is made on a A to C through train; IMO, the literal wording of Condition 13(a)(i) is satisfied in the case of a single A to B journey, although it is even more questionable whether then passenger could subsequently "resume" at B and then travel on to C, since the passenger would then be really trying to "have their cake and eat it"!
The wording of the NRG is, IMO, not absolutely 100% clear in giving a contrary interpretation, and in any case, any conflict between the wording of the NRCoC and the wording of the instructions on how to use the NRG would be resolved in favour of the former, so, in short, my view is that:
a) it is almost certainly not intended to be valid, but;
b) it *probably* is technically valid, assuming the most favourable definition (from the passenger's perspective) of the word "journey" is used.
An analogy of sorts would be a passenger using a cheap 7DS to the next halt combined with a long string of SDRs on a non-stopping express train- this is currently valid, since one ticket is a season ticket and the others are not, albeit that it is clearly not intended to be so.
Of course, the matter is open for debate, and personally I would not be comfortable using a ticket in this manner, notwithstanding that I believe it to be valid.
Isn't UK rail ticketing simple?
