Book 83: Labyrinths of Iron, A History of the World's Subways. was hoping for a MUCH better book. Written in 1981, it was largely the history of the NY, Paris and UK systems. Two chapters at the end devoted to others. I enjoyed the details and especially the description of the diplomacy necessary to make early subways work. Too much details in places, not enough in others. Reissued 10 years later newly subtitled "Subways in History, Myth, Art, Technology, and War" Suspect it was someone's thesis
