The Feather River Route is a rail line that was built and operated by the Western Pacific Railroad. It was constructed between 1906 and 1909, and connects the cities of Oakland, California, and Salt Lake City, Utah. The line was built to compete with the Central Pacific Railroad, which at the time held a nearly complete monopoly on Northern California rail service. The route derives its name from its crossing of the Sierra Nevada, where it follows both the North and Middle Forks of the Feather River. The route is famous for its impressive engineering qualities and its considerable scenic value. All of the route is now owned and operated by the Union Pacific Railroad; however, the Union Pacific has transferred significant portions of the route to other lines.
