Overview
(The information presented here focuses on the railroad properties and tracks. Except for a brief period in 1897-1898, Union Pacific always held full control and almost complete ownership of OSL&UN and OSL.)
In the late 1870s plans were made by Union Pacific officials to begin construction at Granger, Wyoming, on a line which was to take the Union Pacific across southern Idaho into Huntington, Oregon. After making this decision, the Oregon Short Line Railroad Company was incorporated under the laws of Wyoming on April 14, 1881. Immediately surveys and negotiations for a right of way were made and soon construction was started. The road was completed in 1884 to Huntington, where connections were made with, and trackage rights acquired over the line of the Oregon Railway & Navigation Company.
On August 1, 1889, the OSL Railway road took over the Utah Northern, the Utah Central, the Utah and Nevada and other Union Pacific controlled lines in Utah, creating the Oregon Short Line & Utah Northern, a great system subsidiary to the Union Pacific running from Frisco, Utah, in the south to Granger, Wyoming, and Portland, Oregon. It included all the Union Pacific holdings west of Granger, Wyoming, with the exception of the main line track into Ogden. The line operated 178 locomotives, 1,146 passenger cars and 5,871 freight and miscellaneous cars, and the trackage included 1,698 miles and an army of employees insured efficient operation of the line.
In 1893 the Union Pacific was forced into receivership, and a separate receiver was named for the Oregon Short Line & Utah Northern. Early in 1897 this road was sold under foreclosure and reorganized independently on May 16, 1897, as the Oregon Short Line Railroad Company. By 1898, however, the Union Pacific had repurchased a controlling interest, and by the end of 1899 held nearly all of the stock of the Oregon Short Line, which again became a part of the Union Pacific.
Oregon Short Line Railroad (OSL) and its predecessor companies operated all UP lines in Idaho, Montana, and northern Utah.
All OSL lines in Utah were purchased from predecessor companies.
- July 1881 - The original Oregon Short Line Railway began construction at a connection with UP at Granger in southwestern Wyoming
- November 1884 - OSL Ry. completed across southern Idaho to Huntington, Oregon
- August 19, 1889 - Oregon Short Line & Utah Northern Railway incorporated as a consolidation of the original 1881 Oregon Short Line Railway and six other railroads operating in Utah and Idaho.
- February 1897 - OSL was incorporated as a reorganization of Oregon Short Line & Utah Northern Railway, in receivership since October 1893.
- OSL (and later OSL&UN) operated the Oregon Railway & Navigation Company under lease between January 1887 and October 1893.
- January 1936 -- OSL leased for operation to Union Pacific Railroad, along with LA&SL and OWRR&N.
- December 1987 - Oregon Short Line Railroad was merged into the Union Pacific Railroad, at the same time that the Des Chutes Railroad in Oregon and the Oregon-Washington Railroad & Navigation Company were both merged into the Oregon Short Line Railroad. A day later, the Los Angeles & Salt Lake Railroad was also merged into the Union Pacific Railroad, with the one-day delay necessary because the LA&SL was owned by both the OSL and the Union Pacific. Also, the Spokane International Railroad was merged into the Union Pacific Railroad.

A section house and signs were erected at the site, and by 1884 there was a water tower, a telegraph, and possibly a small building used for a railroad depot.
