The Curious Core on Instagram: "The Tehachapi Loop is one of the greatest railway engineering achievements in the world. Completed in 1876, this iconic spiral track was carved through solid granite by more than 3,000 Chinese laborers using nothing more than gunpowder, picks, and shovels. Their incredible skill and endurance made it possible for trains to climb steep mountain grades—an innovation still in use nearly 150 years later. Today, the Tehachapi Loop stands as a testament to human ingenui

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
