The Oregon Short Line Railroad (reporting mark OSL) was a railroad in the U.S. states of Wyoming, Idaho, Utah, Montana and Oregon. The line was as organized the Oregon Short Line Railway in 1881 as a subsidiary of Union Pacific Railway. Union Pacific intended the line to be the shortest route ("the short line") from Wyoming to Oregon. In 1889 the line merged with the Utah and Northern Railway and a handful of smaller railroads to become the Oregon Short Line and Utah Northern Railway. Following the bankruptcy of Union Pacific, the line was taken into receivership and reorganized as the Oregon Short Line Railroad.


Oregon Short Line Railway

The Oregon Short Line Railway was organized on April 14, 1881. The line started from the Union Pacific main line in Granger, Wyoming and reached Montpelier, Idaho on August 5, 1882 and then to McCammon, Idaho in fall of 1882. Between McCammon and Pocatello the line was shared with fellow Union Pacific subsidiary Utah and Northern's grade by adding a third rail to accommodate the standard gauge cars. The line from Pocatello to Huntington, Oregon was completed in late 1884.[1] Access to Portland, Oregon was leased from the Oregon Railway and Navigation Company.[2]

The line was essential because the Union Pacific main line ended in Utah with the Central Pacific Railroad which by that time was part of the Southern Pacific Railroad. Southern Pacific tracks reached El Paso, Texas, and would in, 1883, become a transcontinental railroad in its own right. The Southern Pacific then started routing traffic to the southern line, cutting off Union Pacific. The Oregon Short Line also was meant to halt OR&N continued eastward expansion at the Idaho-Oregon border.

Oregon Short Line and Utah Northern Railway

In 1889, the Oregon Short Line Railway merged with Utah & Northern Railway and 6 other smaller railroads to form the Oregon Short Line and Utah Northern Railway. In 1890 the company finished converting the original Utah & Northern line to standard gauge, a process that U&N had started as early as 1885. On October 13, 1893 the OSL&UN went into receivership with the rest of the Union Pacific holdings. The Oregon Short Line Railroad was incorporated in February 1897 and purchased the property of the OSL&UN later that month. On March 15 the OSL took possession of the line and started operating.

The OSL was independent for a short period of time until October 1898 when the newly reformed Union Pacific Railroad took control of a majority of the board of directors. During the early part of the 20th century the railroad publicized tours of Yellowstone National Park by way of a spur constructed from Idaho Falls, Idaho to West Yellowstone, Montana. In 1938, Union Pacific began consolidating operations and leased for operation a number of its subsidiaries including the Oregon Short Line. The railroad operated under the lease until December 30, 1987 when the OSL was fully merged into the Union Pacific Railroad.
