First public operation after restoration of WP 165 0-6-0.

Western Pacific 165 is a 0-6-0 switching locomotive built by the Schenectady Works of the American Locomotive Company. This engine was used at many of the WP's rail yards, including Stockton, Sacramento and Portola. It was built in November, 1919, for the United Verde Copper Company of Jerome, Arizona, as their number 87. On September 17, 1927, the 165 and three sister UVCC engines were sold to the WP and become the road's S-34 class, numbered 163-166.

On March 1, 2006, the 165 returned to Portola on a museum flatcar, marking the return of WP steam power to Plumas County for the first time in nearly 50 years.
