OHLE, which stands for overhead line equipment, has become a commonly used term in the railway industry. However, there are several other terms that can be used as synonyms for OHLE, including overhead traction, overhead contact system, and overhead electrification. These terms are all used to describe the same function of providing power to trains via overhead wires. Another term that can be used is catenary, which specifically refers to the shape of the overhead wire. Regardless of the term used, OHLE is an essential component of electrified railway systems that provide reliable and efficient transportation for millions of passengers each day.
