A must-have for modelers, Santa Fe Power in Color Volume 3: Electro-Motive Switchers and Four-Axle Hood Units from Morning Sun Books is the third book in a series about the diesel locomotives of one of North America′s most popular railroads. Author Ed Mackinson covers the Santa Fe′s lesser-known locos. Electro-Motive power played a huge role in moving Santa Fe trains whether working fast freights, in the confines of yards or in service on secondary lines. In this volume, we cover the four-axle hood units, from pre-WWII switchers to Warbonnet GP60Ms. Volume 3 is a great photographic resource for modelers and railfans looking for color photos of Santa Fe motive power. Hardcover, 128 pages.
