For the next big advancement in the development of faster and more efficient transportation, the railway industry has to go through a digital transformation. For this, safety is critical. The solution? New, more efficient verification methods. Perhaps the most apparent safety verification method is testing, and indeed, it is still the backbone of [...]
In this, the third and final, blog post on Signal Design Automation we will look at how Formal Verification and automation are used at Stockholm Metro to increase railway safety. The rail-based public transport system in Stockholm, Sweden is relatively complex and diverse with a combination of subway, light rail and heavy rail. It also [...]
In our previous blog post, we looked at some of the challenges commonly faced in delivery of rail control projects and proposed a remedy: the use of detailed and clear requirement specifications that enables automated development and more efficient safety verification. We will now take a closer look at this process for signaling systems design [...]
The delivery of rail control projects often suffers from high costs, unpredictable schedules and delays. Moreover, the life cycle of modern, computerized, signaling systems is often shorter than those of traditional relay-based systems, with higher maintenance costs. At the same time the need for new, more advanced rail control systems is growing, to optimize the [...]

Prover is exhibiting at the RSSI C&S Exhibition in Omaha. We will be showcasing the latest technology within Signal Design Automation. Stop by booth 1239 to learn how your organization can benefit from a more automated process for design, development and safety assessment of rail control software. Prover’s product offering on display includes the Prover [...]
The IRSE International Technical Committee recently published an insightful report on Strategic drivers of change in the signalling industry. It includes the perspectives of both the user and supplier side, and gives an excellent summary of the challenges currently faced by the signaling industry. IRSE views the primary technology drivers to be: Continued emphasis on [...]
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 [...]
