Tognum received a €20 million contract for the remanufacturing of underfloor rail drives. The contract partner of Tognum subsidiary MTU Friedrichshafen GmbH is Veolia Verkehr GmbH, a private operator of regional services in Germany’s bus and rail system.

The basic agreement covers, over the next four years, overhaul of around 360 powerpacks based on Series 183 and 1800 engines. During the remanufacturing process, the powerpacks are disassembled, cleaned and tested, then reassembled using either new or reconditioned components.

Parts, such as the engine, gearbox, cooling system and generator for onboard power, are overhauled by MTU in conjunction with the original manufacturers. A refurbished powerpack does not usually contain its own original parts, but rather identical parts that have already been reworked. Where necessary, some components are replaced by brand new parts, Tognum said.

The remanufacturing process takes 10 days. The overhauled powerpacks are considered new and are covered by the same warranty as brand-new powerpacks.
