An engineering feat—sure to please tourists, commuters, and little listeners alike! How do you build a tunnel through a mountain? It's not so easy—"The devil himself helped the people to build the first bridge!" But that's just what some industrious engineers are going to do much to the pleasure of one small impatient vacationer. Gotthard Pass in Switzerland— the most important connection between southern and northern Europe—is about to get another tunnel. From impatient vacationers, the Saint who the pass was named for, and the first precarious car journey over the mountain to how modern tunnel engineering works and modern trains this book covers the history and the trials and tribulations to enable all things that go.
