Rail Dampers, Acoustic Rail Grinding, Low Height Noise ...

2015-6-4  One well known relevant parameter is the stiffness of the rail pad (rubber pad between rail and sleeper). A stiff (800 KN/mm) pad couples the rail tightly with the sleeper, allowing energy to flow from the rail to the sleeper. In this case the rail vibration will decrease resulting in a high TDR.

Noise and vibration UIC - International union of railways

2021-9-3  Rolling noise Rolling noise is the most common type of railway noise and there are many technical measures that reduce it. High levels of rolling noise arise from irregularities on the wheel tread and rail head, called roughness. Roughness of the rails can be controlled by maintenance grinding and can be further reduced by acoustic grinding.

Wheel Slipping and Sliding RailElectrica : RailElectrica

2013-5-12  Wheel slipping occurs when tractive effort exceeds adhesive weight whereas sliding occurs when braking effort exceeds adhesive weight. In both the situations, it is the adhesive weight playing the most important role. Adhesive weight is defined as the force that can be exerted by a wheel without slipping or sliding. Adhesive weight = Coefficient []

Ministry of Railways (Railway Board)

6.21 Preventive Rail Grinding The 90 UTS rails are having greater hardness and have a tendency of gauge corner cracking due to rolling contact fatigue. This can be prevented by rail grinding to remove the fatigued top layer of rail metal. Many of the World Railways have increasingly adopted this method.
