The Salt Lake City Southern Railroad (reporting mark SL) is a 25-mile (40 km) short-line railroad operating between Salt Lake City, and Murray, in Utah, United States.
In the 1870s, the Utah Southern was constructing a 105-mile (169 km) line from Salt Lake City to Chicken Creek (Juab County).
On March 1, 1897, the railway was renamed the Oregon Short Line Railroad (OSL).
In the 1990s the UP shifted its trains on the Provo Subdivision to the Denver and Rio Grande Western Railroad tracks between Salt Lake City and American Fork.
The UP no longer needed the line between Salt Lake City and Mount (also known as Mound or Point of the Mountain).
