In this study, core technologies are developed for a bogie system to enable the bogie to run on a track that has a steep gradient and sharp curves. The bogie is designed to run on a minimum curve radius of 10 m by developing independently rotating wheels and axles. It is also designed to run on a maximum gradient of 180‰ with reduced noise by developing an elastic pinion. The traction motor power required for a steep gradient is calculated and reflected in the design of the traction system. In addition, a band braking system is developed to improve the braking force while running on a steep gradient track. The developed main parts are tested to evaluate their performance and are subsequently applied to the bogie systems designed to run on a steep gradient and sharp curve tracks. The maximum load on the bogie frame is reassessed by considering the running conditions on a track that has a steep gradient and sharp curves. The safety of the bogie frame is verified through a loading test. Finally, the developed bogie system with the incorporated parts and core technologies undergoes a running test on a roller rig for evaluating its performance.
