When replacing relay interlockings, most conversations start with technology. The better starting point is governance: how do you make sure you can still change parts of the system 20 years from now? We look at what Open Signaling means in practice, and how our Stockholm Metro pilot was designed for replaceability from day one.

Learn how open signaling helps infrastructure managers reduce lifecycle costs, avoid vendor lock-in, and gain greater control of their signaling systems. This webinar explores how open standards, COTS-based architectures, and a competitive supplier ecosystem enable more flexible and sustainable railway signaling.
Engineering is accelerating with AI, but clarity and control are now the real bottlenecks. Learn how executable specifications and formal verification enable faster, more reliable systems.
How can rail projects move beyond manual data preparation? In this webinar, we show how Signaling Design Automation and formal verification enable a more controlled, efficient, and verifiable approach to generating and validating application data.
Prover uses formal methods to make railway signaling provably safe. Our solutions build safe, reliable, and cost-efficient systems that move and protect millions of passengers every day. Through our Open Signaling Initiative, we're reshaping how the industry builds and maintains signaling systems across Europe and beyond. Now we're looking for someone to join us and bring AI, LLMs, and agentic workflows into the heart of how we work and what we build.
Meet Prover at RailTech Europe in Utrecht, March 4–5. Visit Booth 2.509 and join our workshop on migration of signaling systems to PLC-based SIL 4 solutions.
This webinar shares lessons from a pilot project in the Stockholm Metro. It shows how a relay-based signaling system is being replaced with a PLC-based SIL 4 solution to enable safe, open, long-term maintenance and upgrades.
COTS is a key enabler of open signaling, helping railway infrastructure managers move from proprietary systems to open, modular architectures. By using standardized components, operators can reduce vendor dependency, lower lifecycle costs, and create more flexible and future-ready signaling systems.
Prover and BHEPL are bringing Signaling Design Automation to India’s rapidly growing railway sector. By automating data preparation and verification for KAVACH and other rail systems, the partnership aims to reduce engineering effort, improve accuracy, and accelerate safe system delivery.
CentraleSupélec students explored the full lifecycle of railway interlocking engineering during an intensive week with Prover. Using Prover Studio and Prover iLock, they worked with signaling design, safety requirements, formal verification, testing, and simulation in a hands-on railway project.
EN 50716 (the successor to EN 50128/EN 50657) sets the software development and verification expectations for railway applications, clarifying how formal methods and tool qualification contribute to a robust safety case. This session takes a practitioner’s view of applying that framework to real systems and on‑board functions.
