Guideways

Definition

Guideways are specialized tracks or paths that provide support and guidance for vehicles, particularly in systems that rely on levitation, such as maglev trains. These structures ensure that the vehicle stays on a predetermined course while minimizing friction, allowing for smooth and efficient travel. In maglev systems, guideways often utilize magnetic forces to maintain levitation, thus enhancing speed and safety.
