Development of Shinkansen Bogies for Speed Increases

In order to increase Shinkansen speed, development of new rail bogies for improved running safety/stability, ride comfort and reliability was performed. In that, there has been adoption of new configuration elements such as the driving device and axle bearings for the bogies. A first prototype was made beforehand, and bench tests were used to evaluate its performance and long-term durability. Running performance was then confirmed after bogies were installed on a FASTECH360 Shinkansen high-speed test train.
