What is Boji? : Bogie is a component of railway vehicles. Its task is to ensure the movement of the wheels and the rest of the vehicle.
The main purpose of the bogie is to ensure a more harmonious transition of the long-term railway vehicles on the curved rails and to obtain a second spring step in order to eliminate the ties with the irregularities in the rails of the vehicle in the fixed-position train wheel axle with rigid structure and thus increase the comfort in driving. The bogies are responsible for providing better driving characteristics, resulting in less wear on the rail and less danger of derailment. As the number of axles in the bog increases, the positioning of the rail folds in the passage starts to gain more importance.
