FIELD: transport.
SUBSTANCE: invention relates to rail lubrication by contact application of lubricants onto friction surfaces. Grease in the form of lubing cores 1 is applied by rotaprint method on wheel flange 2 and transferred by contact forces to side surface of rail head 3 on entire rail track section. For this solid dry coating composed of lubing cores of the following formula: graphite treated by electrostatic field - 1-50%, bitumen - 1-50%, colophony - 1-50%, ammonium sulphate - 0.5-25%, aerosil - 0.5-25%, polymer treated by electrostatic field - 0.5-25%.
EFFECT: higher efficiency and quality.
