Beneath the streets of London, Paris, New York, and other cities lie massive, underground worlds of tunnels and trains, transporting millions of people. Undergound railways, or subways, are an engineering marvel. But why were they built? And how? Imagine city streets packed with horse-drawn stages, carriages, wagons, and trolleys --and people. Follow Larry Dane Brimner's high-speed tour of the early subways, from London, where Marc Isambard Brunel solved the problem of tunneling by watchinga shipworm at work, to New York City, where Alfred Ely Beach built a secret subway under Broadway. Neil Waldman's realistic illustrations compliment this amazing story and bring to life the early days when subways were first imagined and constructed. Grab your token! Hop on! The train is ready to leave the station.
