The composite powered wheel set comprises two booster wheels and two support wheels mounted on a driving axle. The booster wheels are fixedly mounted on two ends of the driving axle, the support wheels are mounted on the driving axle via bearings, the moving axle is connected to a first transmission device, which is connected to a first power mechanism, and the driving axle is further connected to a train bogie via a connecting device. Booster wheels and booster rails are provided to improve anti-skid performance, so the train will not skid when running on a steep slope or under a heavy traction load. Restrictions on the railway slope, train traction load, and train speed are eliminated to a great extent, and the application scope of the wheel rails is expanded.
