Purchased from the Northern Pacific Railway for A. B. Hammond's Astoria and Columbia River Railway, number 6 came to the SP&S secondhand. It was used as a switch locomotive until 1931 when it was sold to the St Helens Terminal and Dock Co. at St. Helens Oregon. BackgroundThe Astoria and Columbia River (A&CR) ran from Astoria to Goble, Oregon, where the A&CR met the Northern Pacific. In 1907 the NP purchased the A&CR to be a feeder line for the new Spokane Portland and Seattle Railway.{{sfn|Gartner|1990|page=136}} To help the new feeder line handle increasing freight traffic, an NP Switcher was sold to the A&CR on August 7, 1907.{{sfn|Gartner|1990|page=137}} The SP&S took over the A&CR and on February 24, 1911, obtained all A&CR locomotives.{{sfn|Gartner|1990|page=138}} The former A&CR switch locomotive number 1 became SP&S number 6. Construction historyNumber 6 was built for the Northern Pacific by Baldwin Locomotive Works in 1887. Its builder's number was 8617.{{sfn|Gartner|1990|page=206}} Operational historySP&S Number 6 continued with switching duties at Astoria, Oregon. On June 30, 1931 SP&S Number 6 was sold to the St. Helens Terminal and Dock Company. NumberingOriginally numbered NP 386, and then NP 988,{{sfn|Grande|1992|page=277}} the A&CR numbered NP 988 as A&CR Number 1. The SP&S renumbered A&CR 1 to SP&S Number 6. DisposalSP&S Number 6 was sold to St. Helens Terminal & Dock Co (StHT&D Co). Grande Claims that Number 6 then "blew up and was scrapped."{{sfn|Grande|1992|page=277}} However he gives no dates for this. Gartner only states that when the SP&S bought the St.HT&D Co in 1933 that an SP&S locomotive (SP&S 201) had to be brought in.{{sfn|Gartner|1990|page=143}} DiscrepanciesGartner and Grande differ on several dates. Grande gives a build date of 1897. He also states that the date SP&S No. 6 was sold to the StHT&D Co was 1921.{{sfn|Grande|1992|page=277}} Gartner gives dates of 1887 and 1931.{{sfn|Gartner|1990|page=206}} References
