No. 3025 was used as a "crack" (fast) passenger-train engine, and with its massive driving wheels, was able to attain speeds up to 100 miles per hour and - at that speed - pull 12 passenger cars. It probably hauled several name passenger services in California, including the Daylight, the Starlight and the Lark.
In 1952, it was retired from active service. It still has its inside Stephenson link motion and was the first standard gauge locomotive to go on display at Travel Town (in Griffith Park, Los Angeles, CA) that year after being donated to the museum by the Southern Pacific. Today it remains as a static display there.
No. 3025 is the only remaining "Atlantic" type from the SP.
This locomotive looks fairly similar to the original PRR No. 7002.
