2579 was retired from service in 1956 and is currently in display in the Veterans Memorial Park in Klamath Falls, Oregon.
It worked on many different duties for the Southern Pacific system from the early 20th century well into 1956, even handling passenger trains on rare occasions.
At nearly 400,000 pounds and at 71 feet in length, #2579 was utilized for freight on the SP's Portland, Sacramento, Shasta, and Western Divisions.
It was retired from steam freight operations in November 1956 and vacated from the active roster of locomotives in May 1957.
Since then, #2579 has been on display in Veterans Memorial Park along the shores of Lake Ewauna, near the junction of Main Street and US97.
