The axle is a component of the train wheel that connects the right and left wheels rigidly. When the train is operating, the axle receives the load from the weight of the train and other loads such as the load from the interaction force between the wheels and the rail. In addition, there is also a load that arises from the traction motor through the gears and the load due to braking. Geometry and track irregularity causes the loads acting on the axles to become dynamic loads with a maximum frequency and value that depends on the operating speed. On conventional trains, the axles have a solid design to be able to withstand these loads. Along with the increase in train speed, there is an increase in dynamic loads and stability problems arise when the train is moving on a straight railroad. Several studies have shown that reducing axle mass can increase stability and reduce the magnitude of the interaction force between the wheels and the rails. One strategy that can be done is to use a hollow axle, which is an axle with a hole in the middle along the axle axis. The purpose of this study was to obtain the optimal axle dimensions for use on high-speed trains. There are several standards that can be used in designing railroad axles. The standards that will be used in this study are EN13103 and EN13104. It was found that the axle can be hollowed out to a certain diameter depending on the material.
