The SP&S Class A-1 steam locomotives were a group of 5 identical locomotives. They were used in the rail yards at Portland, Oregon, and Vancouver, Washington, from 1907 to 1952. They were replaced with diesel-electric switch locomotives.
Background[edit]
In 1907, the new SP&S needed equipment for regular operations. Company officials wanted 25 freight locomotives and two switch locomotives to start with.[2] The president of the Great Northern Railway advised SP&S officials that his railroad could contribute excess engines.[2] Because of this, only five switch locomotives were purchased for use in the terminal yards in Portland and Vancouver.[2]
Construction history[edit]
All five locomotives in Class A-1 were built by the Manchester plant of American Locomotive Company. Because of the availability of spare parts from the Northern Pacific Railway in Portland, OR, and Pasco and Vancouver, WA,[2] these locomotives were identical to Northern Pacific class L-9 switch locomotives.[3]
Operational history[edit]
All five locomotives were delivered to the SP&S in February 1908.[4] They were initially used in work service completing the North Bank line from Portland to Spokane.[4] Upon completion of the main line, these locomotives were transferred to the terminals for switching service. In late 1942 and early 1943 all 5 locomotives were assigned to the Portland Terminal yards as switch locomotives.[5] In 1946 locomotive number 2 was sold to the City of Prineville Railway.[1] With the arrival of SW9 switch engines 43-45 in 1951,[6] the remaining A-1 class steamers were retired in 1952.
Numbering[edit]
These locomotives were numbered 1 to 5
Disposition[edit]
Locomotive number 1 was scrapped April 25, 1952. Locomotive number 2 was sold to the City of Prineville Railway and renumbered as their number 7 on July 31, 1946. Locomotive number 3 was scrapped January 24, 1952. Locomotive number 4 was scrapped April 25, 1951. Locomotive number 5 was scrapped January 24, 1952.[1]
