PROTECTION METHODS FOR RAILWAY SWITCHES IN SNOW CONDITIONS

Research and Development programs conducted on several different methods of overcoming the problem of railway switches failing in the presence of snow and ice are outlined. The most common method at present is the application of heat by the combustion of fossil fuel. By the application of forced convection heat transfer switch protection under reasonably severe environmental conditions is possible. A novel combustion heater based on the valveless pulse jet engine has been applied to railway switches. A non-thermal method employing a horizontal air curtain has been developed to prevent the deposit of snow in critical areas. Two switches have been designed and developed for field evaluation. Both switches are capable of operation in snow and ice conditions. /Author/
