And how do you propose to stop split ticketing in the instance that my split is a location where I have to change trains anyway.
I buy a First Class Single Ticket from Bath Spa to West Ham via route: Warminster/Salisbury. When I arrive at West Ham, I already have another ticket to continue onto Chalkwell from West Ham. I haven't bought a through ticket as you cannot get tickets to c2c line stations via Warminster/Salisbury. When I get to West Ham, I could just walk up the stairs onto the c2c Platforms, or go out of the ticket barriers and then in again. The chances are that by the time I get to West Ham when I normally do, the ticket barriers will be open anyway
Now here's an interesting technique. I could even use the excuse that I "split" the tickets at West Ham for a toilet break where in the case of West Ham, the toilet is located outside of the station near the entrance. So I could argue, that although I hold 2 seperate tickets, so therefore I am "splitting", I could argue that I am making 2 entirely seperate journey's as technically I have left the station premises to use the toilet outside the station.
It's a catch 22 situation for both sides of the forces on this one I think.
Another example is where I had to buy a ticket from Warrington Bank Quay to Crewe and then Crewe to Chester, as there wasn't a through First Class ticket to Chester from Warrington, Despite
FC‡ being available on both legs of the journey at the time I was travelling. Would I be penalised then for "splitting" because the original ticket I wanted for the class of travel required wasn't available...?! One would hope not
