This is a great book of photographs of when GE rolled out its Diesel locomotive into the NCR yard to replace the Rubicon steam locomotive. Of course the Rubicon pushed the new diesel to the factory engine house. Then several NCR employees try the diesel out with a run across Dayton's South Main Street. It goes on to show the Dayton and South Park steam locos, and much more. Free to download in your preferred format at http://www.gutenberg.org/ebooks/64856
