Looking at the Battersea NLE, the link between Nine Elms and Kennington will* be extremely useful to me when connecting from South West NR services at Vauxhall. Currently I have to go via Stockwell, which is two extra stops and a change.
Is it likely that that Vauxhall NR / Nine Elms LU will be added as an OSI from opening date? I guess the counterargument would be that it’s possibly a little far (800 metres) considering there are other reasonable on-network options.
*Or it would if it weren’t going to be in Zone 1; in reality I probably won’t use it as I resent the NR1-T surcharge.
I’m not aware of any potential OSIs with Nine Elms. Battersea and Battersea Park is likely.
As for zone 1, it’s a nightmare. The developers who are part funding the extension demanded that it be in zone 1, but I’m fully expecting a new dual zoned sausage like the Stratford arrangement. Kennington to Elephant & Castle has to remain in zone 2. The problem of course is that 2 or 3 is the same fare in the Stratford area, whilst 1 or 2 is most definitely not.
I recall reading somewhere that Kennington will become a Boundary Zone 1/2 (can’t find where now; the best I can turn up is an uncited claim on the List of stations in London fare zone 2 Wikipedia page.
A Nine Elms to Vauxhall OSI is admittedly very niche; the walk means that Oval (and stations further south) will be equal or better sticking with Vauxhall LU and changing at Stockwell, and London Bridge (and stations further north) will be better with other options via Waterloo. But as someone who lives between Kennington and E&C and has tried every way conceivable of accessing SWR services from home (none of them particularly seamless), it would be a welcome addition for me 🙂
I’ve also heard that Kennington will be dual zoned, but as I said the problem is the Kennington to Elephant stretch. It’s the first time a journey will be possible along a boundary where the fares are different in each zone.
