An 80 page education outling not only the operation of vintage steam shovels, but also the science and principles in proper excavating and mining. This is a fun to read book, even for us non-steam enthusiasts, but the real interest will be the many vintage plates of steam shovels. Illustrations depict railroad shovels in action, principles of steam shovel operation, and some very nice detailed diagrams for any model railroad aficionado, wanting to scratch build their own autentic model steam shovels. The plates are simply amazing, probably about 25 in all, plus many more detail illustrations.
