Railway Technical Research Institute (RTRI) developed a bogie which has independently rotating wheels and weighs half as light as the conventional one, being intended to improve the stability of hight speed running on tangent section and the curving performance, and to make it available as a next generation bogie on JR narrow lines. The performance of the bogie were testd on roller rig and in field tests. From the measurement, it is verified that the independently rotating wheels using a newly developed wheel profile has a gravitational restoring force and its performance we have expected. From eigenvalue and results of simulation, the influence of modeling level and that of the steering mechanism, and the better running stability of the independently rotating wheels are clear.
