What we do
We turn your rail control project to a success with signaling automation
Railway infrastructure managers need new rail control systems to support increased traffic capacity. Existing legacy systems are replaced with new, digital rail control to reduce headway and conform to interoperability standards such as ERTMS and CBTC.
Prover provides automation solutions that increase the capacity for delivering a fast and cost-efficiently rail control project. With your digital twin and our formal methods your rail control projects are verified 100% safe.
How we do it
Gain control over your railway signaling with the use of a digital twin
In signaling design automation projects, we start by developing a digital twin of your existing systems, future systems and conceptual systems. The digital twin is developed using formal methods that utilize automated simulation and can test and validate every step of your rail control project.
World leader in formal methods and verification of safety critical systems
Prover is a world leader in formal methods and formal verification for safety critical systems. The company was founded in 1996 in Stockholm, Sweden, and has gained extensive experience over the years in its field. Prover is also present in the US, France, Algeria and China. It is privately owned by investors and staff, and has customers in more than 25 countries.
Signaling systems verified
Prover has developed and verified 426 signaling systems across multiple markets worldwide.
Markets
Prover operates in over 25 countries, delivering signaling system solutions worldwide.

Prover’s innovative solution bring benefits to many types of rail control projects
The project formalized Trafikverket’s signaling regulations by translating them into machine readable requirements and building internal competence in formal methods, paving the way for safer, more efficient, and fully digitalized railway signaling.
In this project, Prover enabled a safe and stepwise migration from legacy relay systems to a modern, PLC-integrated Traffic Management System for the Stockholm Metro.
In signaling design automation projects, we start by developing a digital twin of your existing, future, and conceptual systems.
