A speed control and track change detection device for railways is characterised in that it comprises three high-frequency radar sensors located at the vertices of an imaginary triangle and a digital processing device for processing the signals detected by the radars, wherein in the case of the speed control system, both sensors are located at 1 m distance from each other along the axis of the path of the railway and inspect the ground of the infrastructure 2 cm away from the outside of each rail, and according to the temporal offset of the signals obtained the digital processing device estimates the exact speed of the train.
