This book contains drawings of the motive power operating on the Rutland,
Lehigh Valley, and Maryland & Pennsylvania Railroads during the
early part of the first generation diesel Era. Unsurprisingly it includes not
only Steam locomotives but also Gas, Diesel, and Oil Electric locomtoives.
The drawings are essentially blueprints that a skilled employee could recognize, repair, and service equipment that was in use. They also provided unit number data.
This data is something that each railroad had on hand for their crews operating
the trains and the shops in the areas concerned. In the case where repairs
were necessary these were used to help restore damaged equipment.
Due to the poor quality of the originals many of the folios required editing.
This book has 80 pages with 76 Diagrams, Illustrations, & tables.
