SP 6051 was retired on December 24, 1969, and was donated to the Railway & Locomotive Historical Society at the end of the year along with Baldwin DRS-6-6-1500 5208 and EMD F7A 6402, largely through the efforts of SP Vice President Larry Hoyt. All three units were in turn deeded to the CSRM on June 22, 1978, and placed on display near Sacramento Valley Station or stored at SP's Sacramento General Shops until the CSMR was built. SP 6051 was cosmetically and mechanically restored in the early 1980s and is in its original 1955 appearance in the Daylight paint scheme.
