Compagnie des Signaux

Compagnie des Signaux: A specialist in rail signalling solutions

Compagnie des Signaux, an internationally renowned French company, has been a key player in rail signalling for over 120 years. Specializing in integrated solutions for passenger and freight transport networks, it offers turnkey systems for the management and control of new lines as well as existing infrastructures.

With its expertise, Compagnie des Signaux acts as a main contractor and integrator on global projects, often collaborating within international consortiums. In 2024, it regained its independence and its original name after a period under the successive banners of Ansaldo STS and Hitachi Rail STS, by joining the MERMEC group. This partnership with MERMEC, together with the support of BPI and BNP, marks a new era of innovation and international expansion for the company.

The founding values of Excellence, Integrity and Solidarity guide each project carried out by Compagnie des Signaux, which is a world leader in high-speed signalling and a trusted partner for its customers, collaborators and partners.
