With the mergers of the Chicago & North Western and Southern Pacific into the UP, the motive power situation has gone from an easy to understand system to one that causes many sleepless nights for those who keep up on such information. Many UP locomotives have been renumbered after being renumbered to begin with.
This Volume presents a basic locomotive roster current through the end of 1997. Use this book as a general guide to the UP System and its locomotives, and enjoy the spectacle that is the Union Pacific.
