WP 705 Came to the Western Pacific Railroad Museum from Arizona where she spent several years working in the desert hauling freight for short line “Arizona Central” after retirement from the Western Pacific. This explains the faded red paint. 705 was purchased by a group of FRRS members and brought “home” in 2005. Nicknamed the “Mary Kay” due to its pink (faded red) paint, the 705 will be restored as time and money allow. Once mechanical restoration is completed, it will be painted the Perlman Green and Orange paint scheme. For the time being, WP 705 is stored at the museum on display.
