Most of us barely register the tube trains or stations we pass through every day, but for London photographer (and former graffiti artist) Harry F Conway, these are spaces of social significance and beauty. As a life-long north-west Londoner, the Bakerloo line has a special place in his heart as a portal to the city – almost a second home. 

But as Harry’s Kensal Green neighbourhood started gentrifying, he felt the line was changing too – from the seat upholstery to the passengers. So he started taking photos. We asked Harry to pick four images from his new book ‘Bakerloo’ and explain how he came to capture these subterranean moments of London life.
