" [The locomotive] was one of 38 SP built S-12 switch engines. It was one of 6 built in SP's Los Angles shop's as LA Shop job # 8. Weighing nearly 80 tons, and operating at 200 psi steam pressure the 1258 and her sisters were the state of the art of steam efficiency at their time of conception in 1921. She spent most of her life working in the northern California area. Southern Pacific retired all of it's steam power by 1956, and the 1258 sat on the deadline track at Oakland yard waiting for the scrappers torch, when in 1959 she was donated to the City of Martinez as a museum piece. She was moved to Rankin Park in the hills of Martinez, where she sat until being moved adjacent to the Southern Pacific, now Union Pacific main line at the Martinez Amtrak station in the mid 1980's."
