This week sees Leon sitting down for lunch with Christian Wolmar - a noted railway historian who has appeared on TV, Radio, and is a celebrated author to name just a handful of his accolades and achievements.

In this episode, Leon talks to Christian about his latest book release on Crossrail and its inner operational workings - introducing the motivation behind the book and just some of the projects and releases which are explored in the pages. If you've ever wondered about the £19 billion project to revolutionise the railway in the United Kingdom, this is a great listen for you.
