Innovative technology in bogie design-a case study

Summary form only given as follows. Railway transportation means in developing countries should be improved to greet the coming millennium. Most of them were designed and built 100 years ago. Curves and up and down terrain cannot be straightened. Bigger, heavier, longer, and faster trains led to rapid wear of the wheels housed in the barber three-piece bogie. Innovative technology modified it to become a steering bogie by using statistical analysis method. It was proved that the wear of wheels occurred more slowly
