From specification to certification

Rail transport companies like the rail industry face big challenges like increasing traffic volume and growing competitive pressure. This can only be realized by systematically reducing maintenance, operation and investment costs while at the same time increasing the perfomance.

Lower procurement costs call for a decrease of design variety and the use of modular systems. At the same time electronic systems and their cross-linking are getting more and more complex. This goes deep into execution. The development and test of systems and components is often split among more than one site or company. Here, current test systems and methods hit the glass ceiling for both quality and cost.

Berner & Mattner offers valuable support to its customers for this problem. For many years now, our teams of experts have realized demanding projects for train operators and their suppliers. These projects include customized systems in the control and security technique, processes and methods for the development of safety-critical railroad systems as well as systems integration and test automation.

The result of our long-term project experience is a profound and diversified knowledge of railway technology as a whole. Thus our customers benefit from our innovative, flexible and future-oriented solutions contributing to higher safety standards, increased efficiency and cost savings.
