The Central Corridor is a rail line operated by the Union Pacific Railroad from near Winnemucca, Nevada to Denver, Colorado in the western United States.

Amtrak's California Zephyr uses the entire length of the Central Corridor, as part of its San Francisco to Chicago route.

A portion of the route immediately northwest of Denver also has dedicated electrified tracks for use by RTD commuter rail.

The eastern approach to Silver Zone Pass features a near 360 degree horseshoe curve known as the Arnold loop.

Upon reaching Salt Lake City, the line turns south and follows the Jordan River through Point of the Mountain towards Spanish Fork.

Both routes follow the Spanish Fork (river) up a grade in the Wasatch Plateau, cresting at Soldier Summit.

With the decommissioning of the route over Tennessee Pass, the Moffat Tunnel is the highest point on the Union Pacific system.

Even past where the tracks exit the Rocky Mountains, the grade features horseshoe curves in the final descent.
