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

In the current issue of the trade magazine "Signal + Draht" (3/2022), a technical article by PD Dr.-Ing. habil. Lars Schnieder and Prof. Dr. Pawel Buczek has been published.

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.

In their article in the 3/2022 issue of Signal+Draht, PD Dr.-Ing. habil. Lars Schnieder and Prof. Dr. Pawel Buczek, professor of microcontrollers and digital circuit technology at the Hamburg University of Applied Sciences, consider the need for standardization of system architectures in mass transit, outline the basic functional complexes of highly automated rail transit systems, sketch the transferability of standardization approaches to mass transit, and thus demonstrate that automated mass transit can borrow from tested interface standards used by mainline railroads.
