One of the most interesting roads in the world, the Tehachapi loop..🛤

The Tehachapi Loop (English: Tehachapi Loop) is a famous railway engineering structure located in California, USA. Here's its description:

Location: Tehachapi Mountains, California, USA. It is located on the railway line between Los Angeles and the Central Valley.

Purpose: To facilitate trains gaining altitude on steep slopes.

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.

Features:

A train can cross over itself in the loop.

It allows long freight trains, in particular, to easily negotiate the altitude.

It has been in use since the 1870s and is still active.

Significance: Considered an engineering marvel and frequently visited by train enthusiasts.

In short, the Tehachapi Loop is a "spiral railway" structure that allows trains to negotiate steep mountain slopes safely and efficiently.
