This is a pictorial with over 400 roster and action photographs of SP Pacific Lines steam during World War II and the dozen years afterward as the roster declined. Almost all of the pictures show engines at work or at least ready to run. There is a condensed roster and some text, but the main effort was to present caption information that would explain what is going on in the picture - not just what and when, but why.
Photographic examples are included of almost every class of Pacific Lines steam engine that operated in this time span, with chapters on each wheel arrangement. Many of the images were made from negatives that are sixty or even seventy years old, and yet the photograph reproduction is quite good.
