In the third episode of the Justyna Green podcast, I speak to Paul Priestman, chairman of PriestmanGoode. PriestmanGoode is the design agency behind the design of the new Tube for London and the initial concept for Hyperloop so it's no surprise, that in this episode we talk about Paul's great passion - transport design. We chat about everything from high-speed trains and Dragonfly drones to walkable cities and solutions for ageing population. We also discuss how design of public transport can shape cities' identities and how great design tends to be 'invisible'.   Presented by Justyna Green Music by James Green
