The digitalized railway signaling systems of today are becoming increasingly complex with more and more functionality added to make better use of the existing infrastructure, while maintaining the highest level of safety. This also means that the task of assessing the safety and function of these system becomes more and more complex and often constitutes a significant part of the overall development costs.
We have created a white paper where we look at a state of the art solution for automating a significant part of these verification and validation tasks, and see how this solution has been applied to signaling systems in PTC and CBTC environments around the globe.
The basis for this solution is having requirement specifications that captures the signaling rules in a formalized way, enabling automated processing by computer programs. With this in place, we show that the effort for verifying the safety and validating the critical functionality of a signaling system can be reduced to a simple configuration task. This will reduce workload and the safety for modern railroads.

Prover, RATP and Systerel publish the unified HLL 4.0 specification, keeping the rail industry's formal verification language open and free of dialects.
Generative AI has entered railway software engineering ahead of the standards governing it. A new CENELEC draft amendment to EN 50716 doesn't add requirements. It clarifies which existing rules apply when AI drafts specs, writes code, or generates test cases, and why those rules are harder to satisfy with generative models than teams might assume.
Prover, together with NEAT, Schneider Electric, and Pilz will demo real railway interoperability at InnoTrans: three vendor platforms, one interlocking design, live at Prover's booth.
