(Return to OSL Steam Locomotive Roster Index)

The original OSL Railway began construction in July 1881 at a connection with UP at Granger, Wyoming and was completed across southern Idaho to Huntington, Oregon by November 1884.

Oregon Short Line & Utah Northern Railway had been incorporated on August 19, 1889 as a consolidation of the original 1881 Oregon Short Line Railway and six other railroads operating in Utah and Idaho.

OSL was incorporated in February 1897 as a reorganization of Oregon Short Line & Utah Northern Railway, in receivership since October 1893.

Oregon Short Line Railroad (OSL) and its predecessor companies operated all UP lines in Idaho, Montana, and northern Utah.
