They're saying the two tunnels which we currently show stopping here, should be extended a bit to go under Battersea Dogs & Cats Home and stop a bit further beyond at Prince of Wales Drive.
But I'll leave it because (A) I think I'd want to verify it somehow. Can anything be seen at ground level to verify? (B)
Sounds like they're not running trains down there (yet?) so correctness of the tunnels doesn't matter that much to me. I'll let a tunnel buff map it!

I was trying to find where "Maidenhead Mini Golf" is https://maidenheadminigolf.co.uk Judging by the the bing imagery I think it's here.
Also what else are we missing to the east here? Certainly looks like the carpark was enlarged since this was last mapped. Probably the building work we see in bing was finished now.

Massive new lower level entrance area now open (although with some boarded up areas still) New shops, cash machines, toilets: https://flic.kr/p/TLoX1D https://flic.kr/p/TLoWU6 https://flic.kr/p/TLoWKZ difficult to arrange things accurately though. TODO: try to get photos to relate the entrance position to Fennington St

needs survey of the shops and amenities and footway layout inside this mall

not sure what shape this new building is a the back. needs survey
