When vehicles run through curved sections presenting significant twisting irregularities, the wheel load on the front axle on the outer rail may decrease. Concomitant large lateral force in such cases make it easy for the wheel to climb the rail, increasing the risk of derailment. A new type of bogie has therefore been developed to prevent flange climb derailment by controlling the decrease in wheel load. Confirmation was obtained of the satisfactory basic performance of the bogie through a series of experiments. Confirmation was also obtained of the satisfactory performance of the bogie in the operational running speed range through experiments carried out on the RTRI test line.
