Abstract: 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.

Abstract: A semi-automated convoy transport system for vehicles, wherein a first vehicle referred to as leader includes a system for positioning the vehicle with respect to the infrastructure recording the trajectory over which it drives and transmits said trajectory, together with other information, to the rest of vehicles of the convoy that follow it, via a communication channel. The vehicles that follow the leader include a positioning system and a navigation system which, using the data sent by the leader, follow the trajectory travelled by the leader. In addition, the system includes in the vehicles two front plugs and two rear plugs for receiving respective 8-conductor spiral cables and an extensible rod ending in a V-shaped clamp, which allows the resilient spiral cables to be connected to or disconnected from the vehicle in front or behind.
