WHAT KIND OF RAILS TO PUT ON PARTS WITH HIGH DENSITY OF FREIGHT TRAFFIC

KAKIYE REL'SY UKLADYVAT' NA UCHASTKAKH S V'SOKOY GRUZONAPRYAZHENNOST'YU

The problems of rail failures occurring because of heavy-freight-traffic densities that exceed 50 million ton-kilometers per kilometer are emphasized. Numerous data on failures of R50, R65, and R75 rails under various conditions of traffic density and amount of freight are given. The author contends that the trend for traffic-density increase has exceeded the rate at which heavy-duty rails are being laid in place of the lighter rails. The major criticism is that rails are placed under significantly more severe operating conditions than they were designed for. Recommendations are made that track structures with freight-traffic density of more than 50 million ton-kilometers/kilometer per year be divided into 3 categories: 50-80, 80-100, and over 100. Sections in this last category should be equipped only with normally hardened type R75 rails.
