Spokane and Inland Empire Railroad The Spokane and Inland Empire Railroad Company (S.&I.E.R.R.Co.) was an electrified interurban railway operating in Spokane, Washington and vicinity, extending into northern and central Idaho. The system originated in several predecessor roads beginning c. 1890, incorporated in 1904, and ran under its own name to 1929.

Standard Oil of Iowa Standard Oil Company of Iowa was created in 1885 as a subsidiary of the Standard Oil Trust to handle marketing along the Pacific Coast states of Idaho, Oregon, Washington, California, and Arizona. Though named for the midwestern state, it never included Iowa as one of its primary marketing areas. A prior company named Standard Oil of California had been formed in 1877, and was not associated with the Standard Oil Trust. In 1906, Standard Oil of Iowa was dissolved and its assets handed over to a new Standard Oil of California, later Chevron Oil Company, and now the Chevron Corporation. Standard Oil Company of Iowa is thus the original company that is now Chevron.
