Wheel-rail Interaction

Wheel-rail interaction refers to how train wheels and train tracks fit and move together. When a train rolls, the wheels press against the rails, allowing the train to stay on the track and move smoothly. This interaction involves forces that influence the ride’s comfort, safety, and wear of both wheels and rails. Engineers study this relationship to optimize track design, wheel shape, and materials, reducing noise, vibrations, and maintenance costs while ensuring reliable, efficient train operation. Proper interaction is essential for a safe, stable, and comfortable railway system.
