La Locomotive a Vapeur: English Edition

André Chapelon (26 October 1892 - 22 July 1978) was a noted French mechanical engineer and designer of advanced steam locomotives. Engineer of Ecole Centrale Paris, he was one of very few locomotive designers who brought a rigorous scientific method to their design. Efficiency was one of Chapelon's primary concerns in design; some of his locomotives exceeded 12% efficiency, which for a steam locomotive was exceptional. Here the reader will find considerable technical details of steam engine design including a color section of Chapelon's locomotives and others. This is a 'Must Have' book for the serious steam engine enthusiast.
