Oregon Railroad and Navigation Company
The Oregon Railroad and Navigation Company (OR&N) was a railroad that operated a rail network of 1,143 miles (1,839 km) of track running east from Portland, Oregon, United States to northeastern Oregon, northeastern Washington, and northern Idaho. The railroad operated from 1896 as a consolidation of several smaller railroads.
OR&N was initially operated as an independent carrier, but Union Pacific (UP) purchased a majority stake of the line in 1898. The line became a subsidiary of UP titled the Oregon–Washington Railroad and Navigation Company in 1910. In 1936, Union Pacific formally absorbed the system, which became UP's gateway to the Pacific Northwest.
