After @Keiron pointed out, on the routing guide update thread that Feltham to Surbtion was not a vaild via Clapham Junction, I looked it up on National Rail Enquiries App and was amazed at the number of journeys that would show up but were not valid on a single ticket. They didn't even give a combined ticket price. I'm aware people use Oyster and contactless and can make valid but National Rail Enquiries doesn't show that, so I'm excluding it from this trivia question.
In this case there was about 6 of 7 journey possbilieis an hour and only 1 or 2 were valid, with the remaining 5 being not valid on a single ticket.
So can you beat that?
No via points are allowed for this and you must be using National Rail Enquiries,, which, in addition to the routing guide, is the official source for checking if your train itinerary is valid.
