Current computer-based interlocking systems most often have a centralized design, with all logic residing in a single computer. Centralized interlockings are complex to design. Following the general trend in Cyber-Physical Systems, the SaRDIn (Safe Reconfigurable Distributed Interlockings) concept promises a radically simpler solution. The novelty of the SaRDIn concept is a fine-grained distribution of the logic over all processors deployed at the sensors and actuators along the track layout, i.e. within the track circuits, point machines, signals, etc. The advantages and drawbacks of such a solution are discussed, together with strategies to address the main challenges introduced by this concept, namely configuration, re-configuration and certification.
