Derek Whaley has assembled an excellent reference to the railroads in and around Santa Cruz, primarily along the former South Pacific Railroad running North into the Santa Cruz mountains. This book is laid out in several sections, each covers the railroad spurs, depots and other features that once were and what remains. Each of these sections is excellently researched and cited, including maps illustrating the track arrangement at points along the line. This is an excellent reference to the region and the railroads it served. I highly recommend it to anyone interested in the subject.
