CSX Power In Color Volume 4 by Kurt Reisweber showcases the fascinating world of six-axle GE locomotives inherited from predecessor railroads like Chesapeake & Ohio, Seaboard Coast Line, and Louisville & Nashville. This hardcover volume spans 128 pages and is packed with rare and unusual equipment, including four- and six-axle road slugs built from older power, rebuilt locomotives such as GP40-3 and SD40-3, and road slugs operating deep in the coalfields of West Virginia. A must-have for railfans and modelers, it captures the unique power and history of CSX in vivid detail.
