New approaches with modular interlocking replacement
The ever-shortening lifecycles of technology are having a major impact on interlocking lifecycles and their service lives are shrinking. Whereas mechanical interlockings were still capable of dealing with train traffic 100 years after they initially went into service, the latest digital systems are reaching the end of their life after 20 to 30 years. The replacement of the relay generation of interlockings also means that the first generation of electronic interlockings is now due for replacement....
