Thanks for this, and you are right. I was certainly being flip with my throwaway line about Brighton! I guess the crux of the thing is that, even after your description of the benefits, they don't quite feel so compelling that it makes one willing to put up with this continuing grief. With my (yes! selfish and blinkered) Peckham hat on, it feels like:
- Added reliability for trains which in the 8tph days used to be frequent enough for it to not really matter if they were held a few minutes here or there, but which I'll now get fewer of, even if they are a bit longer.
- An improved station, for which read vastly bigger, when at least in the old station I could get very quickly from my (rainy, cold, exposed) platforms either to buses, tube or out into the world very quickly and which now just seems to promise increasing amounts of tramping around.
- The Thameslink changes I can certainly appreciate will be a substantial difference, especially with the frequency, but even that doesn't feel earth-shattering for me: I can already get to Luton, Gatwick, St Pancras and Farringdon without going anywhere near London Bridge, it's just not turn up and go.
So yes, there are benefits for other people at London Bridge, and even other Southern routes, and of course it's impossible to design just so that nobody ever loses out. Perhaps the inner urban stations just have to be those losers for the greater good. But they sure can't be asked to *like* it or suffer it with good cheer in the hope of a better tomorrow.
(And you can't help wondering if there were more tactical things that could have been done to obtain 50-75% of the benefit)
