ABSTRACT OF THE DISCLOSURE An electromagnetic track brake for braking a railway vehicle by utilizing the top of the running rail including a series of elementary contact shoes. An electromagnetic structure including a plurality of annular excitation coils and a plurality of U-shaped ferromagnetic cores which are in vertical alignment with the line of symmetry of the cen- ter of the running rail. The U-shaped ferromagnetic cores are inverted so that the ends of the two legs form a pair of pole faces adjacent the top of the rail. The pole faces are provided with wear-resistant friction material. The U-shaped cores are attracted toward the rail and the wear-resistant friction material on the pole faces engages the top surface of the rail when the excitation coils are energized.
