In early 1869, prior to the completion of the transcontinental railroad, Mormon church leaders began working on the organization of a connecting railroad between Ogden and Salt Lake City. In January 1870 that line was completed, connecting Salt Lake City to the national rail system.
The twenty-mile Union Pacific Railroad (UPRR) causeway across the Great Salt Lake separates the lake into a North Arm and South Arm of different salinities.

The Salt Lake and Utah Railroad, also known as the Orem Line or Orem Interurban, was an electric railroad which operated between downtown Salt Lake City and Payson, Utah, United States. Construction of the main line was started in 1913 with financing provided by A. J. Orem & Company, with Walter C.

You drive over the seven mile causeway to get out to the island, which offers a great view of how much or how little water the lake currently has. The island is a state park and has three campgrounds, lots of hiking and mountain biking trails, and opportunities for viewing bison and other animals.
Tracks today top a 12-mile causeway built in the late 1950s to replace the original wooden trestle, and Class-1 trains cross the man-made embankment carrying critical freight to and from the West Coast.
On , in a ceremony at Promontory, Utah, the last rails were laid and the last spike driven.
The railroad opened for through traffic on , when CPRR President Leland Stanford ceremonially drove the gold "Last Spike" (later often referred to as the "Golden Spike") at Promontory Summit in Utah.
Current operations Today's Utah Railway operates over 423 miles (681 km) of track between Grand Junction, Colorado, and Provo, Utah, of which 45 miles (72 km) are owned, and the remainder operated under agreements with BNSF Railway and Union Pacific.
