Saarbrücken light rail vehicles S1000

Delivery: 2013-2015

In 2012 Stadtbahn Saar GmbH placed an order for modernisation of power and control components for the electrical equipment as well as the power supply for ten dual-mode light rail vehicles of the type S1000 with Vossloh Kiepe GmbH in Düsseldorf. The contract includes an option for another five vehicles.

Thus, the original direct pulse inverters, which were equipped with GTO thyristors, were modified with new traction components in modern IGBT technology. The existing traction control device was replaced by a new modular control device of the new generation.
The on-board converter fitted on the roof of the vehicle was replaced by a converter of the current generation 500.
Moreover, an H-bridge with integrated control, which has been developed by Vossloh Kiepe, was fitted instead of the existing H-bridge with control device.
The devices were assembled and put into service by our assembly and commissioning team in the workshop of Stadtbahn Saar.
