Solutions for the railroad industry

Railroad industry

Guaranteed electrical safety and reliable availability represent prerequisites for smooth railroad operations. This applies to locomotives and wagons just as much as to signaling systems, signal boxes, tunnels and bridge constructions. This means that system solutions are needed that ensure the continuous monitoring of electrical equipment and railroad facilities. Besides this, early warnings must enable troubleshooting before critical conditions arise.
