The Tehachapi Loop (English: Tehachapi Loop) is a famous railway engineering structure located in California, USA. Here's its description:<br /><br />Location: Tehachapi Mountains, California, USA. It is located on the railway line between Los Angeles and the Central Valley.<br /><br />Purpose: To facilitate trains gaining altitude on steep slopes.<br /><br />Structure: The railway line loops back on itself, creating a loop approximately 1.2 km long. This loop allows the train to gain more altitude over the same distance and reduce the grade.<br /><br />Features:<br /><br />A train can cross over itself in the loop.<br /><br />It allows long freight trains, in particular, to easily negotiate the altitude.<br /><br />It has been in use since the 1870s and is still active.<br /><br />Significance: Considered an engineering marvel and frequently visited by train enthusiasts.<br /><br />In short, the Tehachapi Loop is a "spiral railway" structure that allows trains to negotiate steep mountain slopes safely and efficiently.
