Innovative components for traction applications

Keyvisual Traction Drives

The smart answer to the threat of traffic congestion on our highways and in our urban centers is to relieve them with intelligent railway transportation – from trams and undergrounds to regional and local trains, high-speed expresses and long-distance travel wagons and locomotives. Intelligent in this case means they must be safe, highly available, economical and comfortable, and at the same time protect the environment. Rail drive systems from Siemens Mobility make the decisive difference, with innovative solutions like the use of silicon carbide or permanently magnetized motors, and, as such, already provide the greatest mobility in and around the megacities of tomorrow.
