Southern Pacific 5239 (also known as Oregon and Northwestern Railroad 2) was a Baldwin AS-616 diesel locomotive built by the Baldwin-Lima-Hamilton Corporation in September 1950 for the Southern Pacific Transportation Company.[1]

History

Southern Pacific 5239 was constructed in September 1950, and it arrived on the Southern Pacific Transportation Company that same year in 1950.[1] It was one of 51 Baldwin AS-616 locomotives ordered by the Southern Pacific Transportation Company and was the 12th member of the 51 locomotives that were ordered by Southern Pacific being numbered 5228–5278.[1]

Southern Pacific 5239 was retired from service on the Southern Pacific and was sold to the Oregon and Northwestern Railroad in October 1964 where it was used on O&NW as #2.

The AS-616 was suddenly cannibalized for spare parts through the final years of operation, until being stored in 1984. It would eventually be sold to Pacific Northwest Chapter of the National Railway Historical Society in October 1990.[2]

5239 was then later given to National Transportation Museum, St. Louis, Missouri, until it was stored in Tigard, Oregon and was subsequently scrapped in November 2009.[3]
