What Are the Applications of Tungsten Wire in High-Speed Train Tracks?

In high-speed train tracks, tungsten wire is commonly used for the following applications:

Electrical contact wire: High-speed trains require power to drive the motor, and the electrical contact wire is usually made of tungsten wire because tungsten wire has good electrical conductivity and high temperature stability. These electrical contact wires are responsible for providing power to the train, allowing it to move.

Track heating system: In some cold areas, in order to prevent the impact of snow and ice on the track, a track heating system is used. These systems often include electric heating rails whose heating elements may be tungsten filaments. The high melting point and high temperature stability of tungsten wire make it suitable for long-term operation in cold conditions.

Track signaling system: Signaling systems on high-speed train tracks usually use electrical signals to direct the movement of the train. Tungsten filament can be used to make signal bulbs and other electronic components to ensure reliable signal transmission.

Train lighting system: High-speed trains require lighting systems to provide lighting in the carriages. In some light bulbs, especially headlights and taillights used on high-speed trains, tungsten filaments may be used because of their ability to produce intense light and their relative durability.
