Increasing the technological efficiency of clearing the railway tracks of stations from snow

Abstract

   The article analyzes the applied methods of clearing the station tracks from snow and identifies the organizational and technological problems of each. It was possible to determine the main advantages and disadvantages of track equipment and technologies when clearing station tracks of snow. It has been established that the entire fleet of vehicles for the current maintenance of the track in the winter period meets the minimum requirements for the quality of clearing the track from snow – 50 mm below the level of the rail head. And the main restrictions in planning snow removal and snow removal equipment for work are: the useful length of the track, the employment of neighboring tracks, the presence of a field side, passenger platforms, track devices and turnouts.
   The main objective of the study is to improve the combined technology for clearing the railway tracks of stations from snow and to determine the optimal parameters for the operation of cleaning and cleaning equipment.
   It has been established that the thickness of snow during continuous cleaning by a SM-2 snow brush train with wings should be at least 0,12 m. A graph of the dependence of the cleaning time on the length of the path is constructed for cyclic and improved combined technology with different amounts of precipitation. The recommended snow thickness for the proposed technology was determined – 0,15 m. With optimal equipment operation parameters, the combined technology exceeds the cyclic one in the length of the cleared tracks by 2650 m (for one trip of the four-car SM-2) and in the time of work on the site by more than 30 minutes.
