Protection of digital and electronic interlockings

Railway interlockings require special protection because they ensure trouble-free and safe rail transport.  

Modern interlockings use digital network technology to transmit control commands to points, signals or track contacts. This is intended to increase the efficiency and reliability of the system. At the same time, the high proportion of electronic components makes them susceptible to disruptive influences such as surges and lightning strikes.  

With our protection solutions, interlockings are protected against failures and thus safeguard railway operations.

Applications

Protection for interlocking systems

Lightning strikes repeatedly lead to fires or failures of individual components. Further dangers arise from surges as well as permanent and short-term interference from the overhead contact lines. By protecting interlockings, you can prevent the failure of important systems such as signalling and control systems, telecommunications, railway radio and power supply. The failure of an interlocking can lead to delays, train cancellations or, in the worst case, accidents.
