Union Pacific's Big Boys Hardcover Book (KAL01312)

Union Pacific's Big Boys: The Complete History and Restoration (Hardcover) provides a thorough look at the iconic UP 4-8-8-4 locomotives, explaining who they were, why they were created, how they operated, and why they were retired in the 1950s. It traces the development of the 25 engines in the early 1940s and offers essential historical context for railfans and modelers alike.

The book also follows the modern restoration story of No. 4014, from its recovery in a park in 2013 through its rebuild and cross-country tour in 2019, making it a rich reference for both the engineering details and the preservation journey. The hardcover format adds durability for frequent reference on a bookshelf or in a railroad history collection.
