'I can hear the trains go by',
This review is from: The Great Railway Revolution: The Epic Story of the American Railroad (Paperback)
Wolmar is one of those historians who can take a big complex subject and summarize it well and make an entertaining read. ( I'd put Max Hastings and Frank Dikotter in the same category).
US railroads were people, politics and technology - and that's Wolmar's bias, and it makes the book excellent on the social history.
He says himself that technology is only lightly covered, ( it's a big book anyway), like gauges, braking, electrification, where they caused significant shifts. ( I am also interested in railway technology - but that's for another book ! )
PS. My title is from a traditional American song - Boomer's Story. So much about railroads in American songs.
