How do you come to that conclusion? Is there a new definition of the word "to" that I am not aware of?
Ok. I will explain the logic. Point out where I go wrong.
The restrictions say you cannot break your journey unless it is to change trains.
Which means that you can break your journey to change trains.
Now, changing trains is not a break of journey
So the restrictions say you can break your journey in order to do something you do not need to break your journey to do.
But they still say you can break the journey at that point.
But people, seemingly including you, are insisting that they can take advantage of something that is NOT written.
But it is written.
Poorly, sloppily and not meant. But it is still written.
What?????? Okay, so, lets assume a different scenario, I see a sign on a footway that says "Cyclists Dismount" (Cycling on a footway is against the law), what you are saying is that if I logically presume that, as cycling on a footway is illegal, the sign allows me to cycle down the footway, it is contradictory? That's genius!
I have no idea at all where you get that analogy from as it really has no connections or similarities to what we are talking about.
So you are saying, in law, "to change to/from connecting trains as shown on the ticket(s) or other valid travel itinerary." could mean "to do whatever you want"?
Putting words into someones mouth is bad practice when you are discussing something.
So where is this mystical break of journey you are allowed then? Since you don't need it to change trains (as changing trains is not a break of journey).
"Alcohol is not served to customers under 18 except at breakfast." A classic!
All of these phrases are easy to pick apart, but the meanings are quite obvious.
But if you can pick about these phrases to come out with alternative meanings, then it shouldn't matter what the obvious meaning is.
As I said, this is done in law a hell of a lot. Laws are written with a specific intent, but end up being used by police forces as much as possible beyond the intent of the law (as long as they stay within its wording). The actual intended and obvious meaning isn't the only thing that matters. Other meanings also matter.
Now, I am not suggesting anyone actually uses this. Or that you would be able to convince staff of it. But I do find it a bit amusing that the railway companies use every technicality they can to catch people, yet when people try to use every technicality possible to catch out the railway companies somehow they are apparently wrong.
