Each full-color, hardcover book contains hundreds of images - perfect for enthusiasts who want to see how things were, or for modelers who need a color reference. Most volumes are 128 pages long. The varied freight rosters of the St.Louis - San Francisco Railway (Frisco) and the Missouri-Kansas-Texas Railroad (Katy) are reviewed in full color in more than 300 photographs. There's even a handful of passenger cars used jointly by these fallen flags.
