What genius thought that is a good idea?
More of the stopping services from Horsham will swap over, and eventually merge with their intended cross-TL destination of Peterborough; the fact that some have not is due to crew and stock availability.
It would have been nice to see everything transfer in one go, for simplicity's sake, but this was not to be.
From what I have heard many Horley passengers are forced to go via Gatwick as it is often the fastest route (outside peaks and evenings)
Horley does have regular express services to Victoria during off-peak hours, and a number of very good options in the peak, too (and not necessarily too busy, depending on train). Personally, I think Horley passengers tend to overcomplicate things at times, but there we are. Anecdotally (from myself and others), there are often more complaints from them about waiting at Gatwick than at Horley!
I thought this was an "urban myth" and they are allowed to split the tickets as technically it is separate operating legal entities all controlled by Govia Thameslink Railways ready for the big break up in 2021!
As above, these are not separate entities and even the branding is allowed to merge between routes on some occasions. Eg. GX 387s used on Southern services, and 377s used on a few GX services.
To any GTR controller, apart from some continued fragmentation in the locations of GN and its service delivery staff, it is much easier to swap a lot of things between brands, compared to how a passenger will see it. If you have competent Southern staff to work a GX 387 on an all-stations service via Redhill, for example, they'll do it (and that happened only a couple of months ago).
The colour of paint, in and of itself, makes absolutely no difference when it comes to keeping the job moving, and in that regard the GTR situation is at least much better than having fragmentation between Southern / FCC (remember them?
) etc.
This does make it all the more nonsensical that you can have brand-specific fares. It looks like GTR are also being pushed further and further towards making GX tickets more exclusive, to the degree that they are regularly advertising that GX will
not accept Southern tickets even during major disruption, including when there would be little benefit deliberately boarding GX, as most of their services are quite vulnerable to cancellation if an incident occurs!
