<p>The invention relates to a device for detecting a short-circuiting bridge between or across rail bars of a section of a railway, comprising a first arm that can be brought into electrical contact with a first rail bar, a second arm that can be brought into electrical contact with the other rail bar, an electrical supply source, and detection means for detecting and monitoring, during operation, the short-circuit resistance of the short-circuiting bridge realized by said two arms between said two rail bars. According to the invention, a device of the kind mentioned above is characterised in that it is further provided with a signal generation means which provides a signal to one or both or the rail bars on the basis of the detected short-circuit resistance. The signal generation means provides a signal to one or both of the rail bars. This signal propagates itself through the relevant rail bar and can be detected at a relatively great distance from the short-circuiting bridge or crossbar, for example by means of a receiver that identifies the signal. The railway workers present there can then ascertain in a simple manner whether the short-circuiting crossbar is indeed present in the railway section in question. Any confusion owing to miscommunication regarding any other parallel railway sections that may or may not be short-circuited is thus avoided. It can be ascertained by means of said signal whether the railway section is in the safe, short-circuited state and can be safely accessed by the railway worker(s).</p> |
