In it the author explores the rapid transit systems of New York City, Los Angeles, Phoenix, Paris, Copenhagen, Moscow, Tokyo, Bogota, Portland, Vancouver, Toronto and Montreal.
All of these cities, including my own, have a combination of busses and rail as part of a larger public transportation system.
What was interesting was how some cities get the rail right and others simply don't. It was interesting to learn how each system came about and how they evolved.
I read this book entirely on my commutes and felt pretty good about myself in that I am using a system that will play a bigger part in our lives in the future.
Not only was it informative on the subject of transit but it also worked as a travel book. In each city the author gives a history of the city and a bit of the flavour and how the population lives.
I liked the book very much.
