Coning of wheels is provided to:
1. Check lateral movement of wheels:
Coning of wheels refers to the gradual inclination of the tread of railway wheels. The outer diameter of the wheel is slightly larger than the inner diameter. This coning ensures that the wheels naturally tend to move towards the center of the track, reducing the possibility of lateral movement. Lateral movement of wheels can lead to derailment, which is a serious safety concern. By providing coning of wheels, the lateral stability of the train is enhanced, reducing the risk of accidents.
2. Avoid damage to inner faces of rails:
When a train is in motion, it exerts a significant amount of force on the rails. Without coning of wheels, the entire weight of the train would be concentrated on the inner faces of the rails. This concentrated force can lead to wear, deformation, and damage to the inner faces of the rails. By providing coning of wheels, the load is distributed more evenly across the rail head, reducing the potential damage and prolonging the lifespan of the rails.
3. Avoid discomfort to passengers:
Coning of wheels also helps in providing a smoother and more comfortable ride for passengers. When the wheels are coned, they naturally align with the track and follow the curvature of the rails. This reduces the lateral forces acting on the train and minimizes the vibrations and jerks experienced by the passengers. A smoother ride enhances passenger comfort and reduces fatigue during long journeys.
Conclusion:
Coning of wheels is a crucial design feature in railway systems. It serves multiple purposes, including checking lateral movement of wheels, avoiding damage to inner faces of rails, and providing a comfortable ride for passengers. By ensuring that the wheels naturally align with the track, coning enhances the safety, stability, and longevity of railway systems.

The below diagram show cross-section of the permanent way as per Indian Railway Standard:
Coning: Inward provision of the slope of 1:20 on the wheels of the railway wagon to counteract the centrifugal force acting the on the train. So, it enables the train wheels to cover different distances along the inner and outer curves simultaneously.
Purpose of coning:
1. To check lateral movement of wheels
2. To avoid damage to inner faces of rails
3. To avoid discomfort to passengers
