What started off as a hobby tube map collection, became a documentary. This week Steven chats with Anthony Norris-Watson, a non-geographer, with a collection of over 260 London tube maps about his new documentary Interchange. Anthony’s fascination with the tube diagram is obvious as he passionately discusses this three part YouTube doc that focuses on the map designs throughout the years, a discussion on what makes them 'iconic', and a look at how tube mapping may change in the not-so-distant future. Listen as Anthony explains how his love for tube maps began, what he learned along his journey, and how he would improve the diagram.
