8A bold railroading technology and its fate. Are there any other better words to describe it? Turbine Power by Walter Simpson is a new book that covers steam and gas turbine locomotives and trains, how they functioned, and the technology used from the 1939-2003 era that made them go. This is the first book that brings together information about turbine locomotives and trains that collects all of the various projects in one place. From first prototypes to the most recent proposals, everything is presented with vintage images and references that all railroad fans will enjoy.
