ABSTRACT:
An electromagnetic track brake for a railway vehicle comprises an elongate brake energizing coil (1), an oval frame (2) thereabout, and a plurality of U-shaped shoes (3) mounted in a row on the frame. In order to improve the working characteristics and the stiffness of the track brake the lower branch of the frame (2) has a closed cross-section and an interlocking portion (15) extending down between the U-legs of the shoes (3). Interlocking elements are provided on both the frame and the shoes for transmitting braking reaction forces from the shoes to the frame.
