Track alignment

Definition

Track alignment refers to the precise arrangement and positioning of the guideway or track used in maglev systems to ensure safe and efficient operation. This involves aligning the magnetic levitation elements and the track structure to minimize lateral forces and enhance stability during travel. Proper track alignment is crucial for maintaining the levitation effect and achieving high-speed travel without excessive vibration or deviations.
