Abstract: A train detection system for a railway track defines a first lateral side and a second lateral side opposite the first lateral side. Two cameras are arranged along the railway track spaced apart from each other. Each camera is placed on either the first lateral side or the second lateral side. The system includes at least one passive target. Each of the passive targets is placed within the field of view of at least one of the cameras and on the opposite lateral side of the railway track with respect to the at least one of the cameras in whose field of view the respective passive target is placed. The system also includes at least one controller adapted to recognise the passive target in the images provided by at least one of the cameras to the controller to determine whether a train is located on the railway track.

Abstract: System for determining train information relative to a train moving along a railway track having a pressure measuring device placed along the railway track and arranged to measure the speed of an airflow generated by the train when moving on the railway track, and to generate a speed signal; and a controller arranged to receive said speed signal and to determine train information relative to the train in function of said speed signal.
