Software testing isn’t just about apps and web services — it’s also about ensuring the safety of real-world systems. Taras, a test engineer at Siemens, takes us inside the high-stakes world of railway system testing, where software meets physics, mechanics, and strict regulatory standards. We’ll explore how modern rail networks operate, the complex interplay of automation and control systems, and why testing in this domain is more than just debugging—it’s about preventing real-world failures. Expect an interactive deep dive into how railway traffic is managed, the challenges of certifying high-risk systems, and the technical depth required to keep trains running safely and efficiently.
