The American Steam Locomotive In The Twentieth Century PDF Download

Like many other books, Articulated Steam Locomotives of North America began as a modest attempt to chronicle a certain type of locomotive---in this case, the Mallet-articulated locomotive in the U.S.A. This project soon ballooned into unanticipated magnitude. It wasn't long before it became evident that Canadian and Mexican engines could not logically be ignored; they were an important part of the story. After that, one thing quickly led to another. By including the double-truck Fairlies, one was obliged to recognize their single-truck counterparts, as well as several mechanical hybrids which defied accurate classification. Locomotives having geared trucks were indeed articulated; thus, something had to be said about them. Then, there was the booster-engine which temporarily transformed ordinary locomotives into pseudo-articulateds. The latter-day duplex-drive locomotives could properly have been omitted; however, that would have concealed an important episode of motive-power progress wherein one railroad tried to avoid articulation. Consequently, duplex-drive locomotives are included, too.The author's efforts to locate suitable photographs to illustrate this chronicle have been remarkably successful--and there have been few locomotives whose portraits have been completely elusive. Considering the objective was to obtain views of every kind of articulated steam locomotive on every major railroad, this was no easy task. However, the end result is a dazzling collection of over 600 photographs--including more than 32 color views--some of them quite rare.
