The invention refers to a brake for rolling railway cars preferably for shunting purposes and it incorporates an actuating member (3) adapted to be given a movement by a passing railway car wheel, which movement via a speed dependent coupling (7, 8, 9, 10) is transferred to a mechanical braking device (14, 15, 16) when the speed of the movement exceeds a certain pre-set value. |
