HIGHER SPEEDS THROUGH CURVES

Investigation of rail friction (mu (sub y)), made on both wet and sanded rock, at speeds between 6 and 72 km/h, showed values ranging between 0.4 mu (sub y) and 0.5 mu (sub y) with banding leading to higher values. Values of mu (sub y) for lateral slip versus wheel-load are given as are values of mu (sub y) for a range of R(m) from 300 to 890 at speeds from 80 to 110 km/h. It was noted that the use of bogie intercouplers reduce rail friction (mu (sub y)) and flange wear.
