Tehachapi Loop

Pacific's Tehachapi Loop was an engineering marvel of its day and remains an important artery of the Union Pacific system today. The loop was constructed in the latter half of the 19th century as part of Southern Pacific's main line through southern California, which had to cross the Tehachapi Mountain range. Its intent was to gain elevation at a manageable gradient and has worked so well for nearly 125 years that it has remained virtually unchanged and in regular use. When the hobby of railfanning began to gain steam in the mid-20th century folks flocked to the site to not only watch the trains cross over themselves but also for the area's stunning scenery.
