Locomotion No.1: The British Train That Shaped the Future! Guy gets stuck into the oily and clever engineering behind Stephenson’s Locomotion No.1 . He helps build a fully working replica for its 200th anniversary and takes on the challenge of driving it along the original Stockton & Darlington route. This is The British Train That Changed The World – watch now on Channel 4. A proper watch, this. #guymartin #trains | Guy Martin
