Open communication interfaces for Automatic Train Control systems – a vision or reality?

March 2022 | Lars Schnieder, Paweł Buczek

In the last few decades, Communications-Based Train Control systems (CBTC) have established themselves as the de facto standard both for new construction projects and for signalling renewal in existing high-performance urban rapid transit systems. Since the functional scope of these train control systems is largely described by standardisation, various manufacturers’ system solutions are therefore comparable, at least in this regard. Nevertheless, the operators’ perspective sees a need to counter the manufacturers’ proprietary system solutions with a system concept based on open interface standards....
