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: A railroad track circuit determines occupancy status of a portion of a railroad track, and includes: a track including first and second rails; a transmitter including first and second connection terminals to generate a voltage between connection terminals; and first and second receiver units, each including first and second measurement terminals, the first and second receiver units measuring voltage between first and second measurement terminals. The output connection terminals of the transmitter connect to the respective rails at a first connection location, using first and second cables. The first measurement terminal of the first receiver unit is connected to the first rail at a second connection location, using a third cable and the first measurement terminal of the second receiver unit is connected to the first rail at a third location, using a fourth cable, the second and third locations forming respectively first and second boundaries of the track circuit.

Abstract: A wayside communication system for transmitting coded current signals through running rails of a railroad track between wayside control devices. A power line common to the wayside control devices is used as the return path for the current signals. The system features train and broken rail detection. The system allows sending signals long distances since rail to rail current leakage is no longer an issue.
