When the first passengers climbed aboard the earliest ever underground train in 1863, it would have been impossible to imagine how the London Underground would change and grow over the next 150 years. From smelly steam trains running along a single track to the innovative electric tube system speeding through a vast network of tunnels beneath our feet today, the London Underground keeps this busy city on the move. This title tells the extraordinary history of the world's most famous underground railway. Explore Victorian London as the Brunels dig deep under the Thames. Take refuge in the tunnels during World War II and discover which world leader's bath was found in an abandoned station.
