The Tehachapi Loop is a 0.73-mile (1.17 km) long "spiral," or helix, on the Union Pacific Railroad line through Tehachapi Pass, of the Tehachapi Mountains in Kern County, south-central California. The line connects Bakersfield and the San Joaquin Valley to Mojave in the Mojave Desert. Seeing a daily average of almost 40 trains, the line is one of the busiest single-track mainlines in the world.


With its frequent trains and spectacular scenery, the Loop is one of the prime railfan areas in the country. In 1998, the Loop was also named a National Historic Civil Engineering Landmark.
