I reckon it's more to do with people flow The recent upgrade to transport makes joined up sense. It's just easier to get to the area now, and the Ginger line brings a flow of affuluence among its commuters. Canary Warf, Shoreditch and the likes are now easy peasy for those who work there. A bit like snakes & ladders: Priced out of Hackney? then slide down the line to Peckham, Penge, Brockley, even Sydenham I accidentally got on the wrong train from Shoreditch yesteday and ended up at Queens Town Road. You know the place, the one with the trendy bakery and the craft ale Beer Rebellion bar, where I got a black cab from right outside the station Yer, whoooo'd have thought it. It's all change and it ain't going backwards
