Southern Pacific's Streamlined Articulateds: The Iconic AC-9 Class (Southern Pacific Cyclopedia)

This book features a photographic anthology of Southern Pacific’s iconic AC-9 class articulated steam locomotives. Unlike SP’s famous cab forwards, the AC-9 class was designed for operation as coal burning engines on the Rio Grande Division. Ordered shortly after SP’s streamlined Daylight locomotives, the dozen AC-9s from Lima also featured a skyline casing and were the only semi-streamlined articulated engines ever produced. Many previously unpublished images are supplemented by historical information, technical specifications, and tender records. It has 174 photos and 152 pages. Price $29.99.
