Spokane International Railway

Union Pacific acquired control of the Spokane International Railroad on October 6, 1958. Spokane International Railroad was formally merged into Union Pacific Railroad on December 31, 1987. UP originally held about 99 percent of SI stock, and gradually acquired the remainder. In 1959, Spokane International's equipment (including the 11 RS-1s and four remaining cabooses) was first leased, to UP, then later actual ownership passed to UP.

Spokane International Wooden Cabooses

Spokane International owned at least ten wooden cabooses with steel underframes, numbers C-8 through C-17. SI C-9 was a former GN caboose; SI C-13, C-14, and C-15 were former NP cabooses; C-10 may have been either an ex-GN, or an ex-UP caboose; and C-17 was a former UP CA-1 caboose. These cabooses were all retired, between June 1959 and February 1966, with the arrival of the steel ex-UP cabooses.

In outward appearance of Spokane International's wooden caboose fleet, C-1 through, C-6 were similar in appearance; C-9 and C-10 were similar in appearance; and, C-13, C-14, and C-15 were similar in appearance.

SI C-17 may have operated briefly as SI 3240 (its former UP number) upon its arrival.
