Systems Design

Competence and know-how

The system engineers of Rail Power Systems apply their competence and know-how to come up with solutions for powerful, economic and long-lasting railway power supply systems for mass transit and main lines.

System: Bringing together what should be together

Everything you need for railway power supply

Rail Power Systems and the experts of its System Technology division ensure that the power supply for standard-gauge railways and local traffic systems is designed optimal, economically and environmentally clean and that all systems and platform developments are integrated. They are assisted by state-of-the-art computer applications, virtual simulation programmes, precise feasibility analyses and sophisticated project software tools.
