In 1954, an GE 50 Ton diesel locomotive was purchased, relegating steam power on the Southern Pacific's narrow-gauge line to backup duty. Locomotive #8 was retired in 1955 after 48 years of service and donated to the State of Nevada. Now owned by the Nevada State Railroad Museum, it has been on display at Lillard Park at Sparks, Nevada since 1975 after negotiations of a long-term loan.[2]
