You could argue the tube network is one great piece of art. That's how Luke Agbaimoni sees it.
The photographer spins workaday moments on the network into powerful vignettes: station signs are liquified in puddles. Fast-moving commuters become ghosts through the camera lens. Walkways and tunnels transform into portals from a sci-fi film.
Agbaimoni has now turned select images from his impressive portfolio into a book: The Tube Mapper Project: Capturing Moments on the London Underground.
The design and architecture of the stations create the backdrop, but you feel that the unaware, anonymous commuters are the real stars of many of these images; frozen in moments of waiting, rushing and daydreaming, which all of us are familiar with.
In one of the photos, taken at South Kensington, we're even left wondering what a certain pigeon's story might be.
The Tube Mapper Project: Capturing Moments on the London Underground by Luke Agbaimoni is on sale now, RRP £20.
