The aim of the Tehachapi Loop was to gain elevation at a manageable gradient, and this has worked so well for nearly 140 years that it continues to be used even today. In fact, it one of the busiest single-track mainlines in the world with an average of almost 40 trains passing through the Loop each day. The frequent trains and the spectacular scenery makes the Loop a prime draw for trainspotters in the country. The engineering feat has earned the Loop the dual status of being a National Historic Civil Engineering Landmark as well as a California Historical Landmark.
