Preserved Western Pacific diesels at Portola, California, on May 10, 2008 capture the spirit of another era. This image appeared in my 2009 title Railroads of California published by Voyageur Press. The photo was exposed on Fuji Velvia 100 slide film using a Canon EOS-3 and 100mm f2.0 lens. WP 608 is an Electro-Motive Corporation model NW2 built in 1940 for Union Pacific, and later acquired by WP. While WP 707 is a GP7 bought new by the railroad.
