Abstract

The results of investigations concerning the laser cleaning of polluted rail track and its productivity analysis are presented. The laser applied in the experiments is Q-switched pulsed Ytterbium fiber laser (average power of 50 W, pulse duration of 100 ns). The contaminations were put both on rails of P65 mark and bandages. The estimation of laser cleaning efficiency revealed that there is a possibility to increase the coefficient of friction between the rail and bandage by 30%.
