Trains have been the main means of transportation in the world for a long time. Therefore, the progress and design of trains has been a widely debated topic, and how to reduce the wear and tear of trains is a major aspect. There are many factors that can affect the resistance of a train as it moves. Including but not limited to Locomotive shape, the smoothness of the connections between the carriages of a train, the wheel axle and the adsorption device under the train and the train’s relative velocity with respect to air. This paper will study two main aspects of train fluid resistance. The first is the locomotive shape, that is, the effect of differences in the external shape of the train on the surrounding fluid. The other is the speed of the train, which is the influence of the relative speed of the train and the surrounding air flow on the surrounding fluid.
