I guess soIs the incentivd to solely increase revenue within there network and/or starions they manage?
Furthermore, various TOCs seem to be keen for people to book 'direct' and not to book on sites such as ours; sites such as ours will reduce revenue for TOCs such as GWR, as we often find cheaper combinations of tickets for their premium journeys.
Some people appear to be prepared to pay for higher fares providing they get some sort of 'freebie'; LNER and GWR absolutely aim for that sort of market.
Although TOCs such as GWR are known to come out with anti-splitting nonsense, and are keen to avoid people splitting at places like Didcot etc, they do want to encourage people to split at the point where you change off their services and onto other operators, as this means they get to keep 100% of the revenue on those segments.It's actually more closed than that - "Travel must be between two stations served by GWR on services operated by GWR" and "used by you between two stations served by GWR, on services operated by GWR.".
So even a booking that has a short connecting hop, like Swindon to Cardiff Bay, where the journey is nearly all with GWR, wouldn't count.
Of course, this makes very little sense, but then a lot of what some TOCs do - when it comes to fares and ticketing matters - comes under that category.
Before people rush to join this scheme, and split all their tickets at start/end of the GWR segments of their journey, do also bear in mind that GWR charges admin fees for changes/refunds based on a 'per ticket' basis, not based on the whole booking, so any changes/refunds could end up being very costly.
