After nearly three years, Luke Agbaimoni returns to #RailNatter to talk about his second book, "London Underground Symmetry & Imperfections". Once again, he's given us a tease of some of the photographs we can find in the book, and we walk and talk our way through each, exploring the aesthetic sublime of London's public transport systems.

Make sure to follow Luke on Instagram, and you can find links to buy Tube Mapper Book 2 here: https://tubemapper.com/tube-mapper-ph...
