Los Angeles and Salt Lake Railroad

The Los Angeles and Salt Lake Railroad (reporting mark SLR) was a rail company in California, Nevada, and Utah in the United States, that completed and operated a railway line between its namesake cities (Salt Lake City, Utah, and Los Angeles, California), via Las Vegas, Nevada. Incorporated in Utah in 1901 as the San Pedro, Los Angeles and Salt Lake Railroad, the line was largely the brainchild of William Andrews Clark, a Montana mining baron and United States Senator.
