Background

The Astoria & Columbia River Railroad ran from Portland, Oregon, to Astoria, Oregon, along the south bank of the Columbia River. In 1896-97 several locomotives were obtained secondhand for the newly completed line. Among these locomotives were A&CR numbers 6 and 7. These locomotives would become the two members of Class L-4 when the SP&S bought out the A&CR in 1911.

Numbering

Upon the acquisition of the A&CR by the SP&S both locomotives were renumbered and placed into Class L-4. A&CR number 6 was renumbered SP&S number 53 on February 24, 1911. A&CR number 7 was renumbered SP&S number 54 on February 24, 1911.[1]

Disposition

SP&S number 53 was sold to Warren CC on May 6, 1920. SP&S number 54 was dismantled in May 1924.[1]
