How Everything Works on Instagram: "The Tehachapi Loop is one of the most significant achievements in 19th-century railroad engineering. Completed in 1876, the project formed a crucial section of the Southern Pacific Railroad’s route through the Tehachapi Mountains, linking California’s Central Valley with the Mojave Desert. To overcome the steep elevation change in this rugged terrain, engineers designed a 0.73-mile spiral in which the track crosses over itself—an innovative solution that allow

FACT NEXUS on Instagram: "The 'Tehachapi' Loop was built as an ingenious spiral track by Southern Pacific Railroad in 1876, designed by William Hood to help trains climb the steep Tehachapi Mountains with a manageable grade (2.2%), allowing them to gain 77 feet in elevation over a 3,779-foot circular path through solid rock and tunnels. Primarily with help from Chinese laborers, connecting the San Joaquin Valley to the Mojave Desert for the first railroad linking LA and SF. #science #technology
