This title features Southern Pacific?s operations from LA to Bakersfield during the period between mid-1930 to the 1950s. You?ll enjoy the large collection of SP photos of many vintage photographers, each photo featuring detailed information on the history of each locomotive. This is Dave Houston?s second SP book and it gives a glimpse of what was running during that time period. Huge Cab-forwards, as well as ?normal size? steam locomotives, and early diesel units are featured throughout this very interesting new title.
