ABSTRACT OF THE DISCLOSURE A concrete sleeper for track systems incorporating electrical circuitry, in which sleeper electrically conducting cables are embedded, and therefore concealed therein, with means to allow electrical connection between the cables and associated tracks and associated track side circuitry. In order to obtain connection to the track side circuitry a recess is provided in one end of the sleeper and receives a terminal box having contacts for contacting exposed ends of the embedded cables and connections within the terminal box are in turn connected to the track side circuitry. In order to achieve an electrical connection with the tracks the cables are connected, within the sleeper, to embedded parts of shoulders of rail fastening assemblies of the type marketed under the name PANDROL. - 1 -
