This results in low efficiency and numerous safety hazards. Furthermore, the braking effect of the retarder in the marshaling yard is also very limited. The intelligent electromagnetic braking system of the present invention, however, can intelligently and remotely control the precise braking of any railway freight vehicle within the station by leveraging the magnetic attraction of the rails to the wheelsets.
