Abstract
The paper presents the problems of operating railcar retarders at hump-assorting complexes. To solve the problem of noise when braking freight cars at braking positions, it is presented the data on noise measurements during the retarders operation, and it is considered the reasons and conditions for its occurrence. Analysis of noise level measurements and subsequent ranking of frequencies made it possible to identify the most significant octave frequencies responsible for the noise level from the braking positions. A design has been proposed for the mechanism of the contact-rotaprint method of applying a friction modifier to the end surface of a car wheel to reduce noise during braking. Peak sound pressure values have decreased to values that are fully consistent with the required standards specified in sanitary standards.
