: These systems are designed to minimize "play" between the tractor and the trailer, reducing wear and improving safety during transport. 3. Historical Curiosity: Yarmolchuk’s Ball Train

: Unlike standard trains, bullet trains typically run on exclusive high-speed tracks with large-radius curves to maintain velocity. 2. Agricultural Machinery (Ball Hitch System)

: The pioneer of this technology, known for its punctuality and speeds exceeding 300 km/h.

The term is most commonly a direct translation of the English "bullet train," referring to high-speed rail systems characterized by aerodynamic "bullet-shaped" locomotives.

A more literal "ball train" was an experimental Soviet project in the 1930s designed by Nikolai Yarmolchuk.
