Experimental and numerical studies of the effects of a rail vibration absorber on suppressing short pitch rail corrugation [PDF]
, 2016 The effects of a rail vibration absorber on suppressing short pitch rail corrugation are studied. Firstly, a rail vibration field test is carried out to analyze the vibration response of the rail with and without the vibration absorbers.

Assessment of rail long-pitch corrugation
IOP Conference Series: Materials Science and Engineering, 2017 The paper focuses on defects of the running surface of the rail, namely the rail corrugation defect and specifically long-pitch corrugation in curves of small radii. These defects cause a shorter life of the rails, greater maintenance costs and increase the noise and vibration pollution.
