Abstract

A safety device (1, 31) for use with a railway signalling interlock arrangement is provided with two instruction receivers (3a, b 33a, b) each for receiving from a central interlock unit (6) one instruction which instructions have the same meaning but may have different forms, and switching in common to enable selected settings of a group of settings of a device (2, 32) for controlling the railway traffic to be made, e.g., the settings of a signal light in which the green signal lamps (2a, b) are illuminated. The safety device comprises means (8a, b 38a, b) for bringing about the switching, and a further third instruction receiver (3c, 33c) for controlling switches (20a, b 48a, b) for setting the device (2, 32) for controlling railway traffic in a specific one of the enabled settings, e.g., the illumination of two green signal lamps (2a, b). The safety device (1, 31) is further provided with sensing means (11-18 50-53) for transmission to means (5) in the central interlock unit (6) of information relating to the kind of initiated setting. Each of the two first mentioned instruction receivers (3a, b 33a, b) is arranged to revert to a disconnected state and thus inhibit the initiated setting upon receipt by anyone of them of instructions to that effect from the said means (5), which is arranged to deliver such instructions when it is established that the initiated setting is incorrect.
