YouTube star Geoff Marshall reveals how and why he started making great quality, informative, interesting, fun transport films which have attracted more than 82 million views on his channel and are appreciated by his 314,000 plus subscribers.

Geoff travelled to all 2,563 trains in the UK followed by Ireland's 198 and held the Guinness World Record twice for visiting every London Underground station in the fastest time!

He shares his YouTube story, his passion for transport, chats about his new stand-up show - World’s Biggest Tube Nerd – and, in a rare contemplative moment, talks about a moving film he made about how travelling by train can sometimes help when people feel low.
