Dieselhydraulische Lokomotive G 2000 BB - Entwicklung einer Lokomotivplattform

摘要

The liberalization of the railway market in Europe in the 1990s created a need for new means of traction. The G 2000 BB locomotive platform has made use of familiar technologies to create new eight-wheel diesel-hydraulic line locomotives. Its simple structure and the modular arrangement of its functional groups make it possible to keep down the costs of operations and maintenance and to adapt it to a broad spectrum of requirements. Up until now, 64 locomotives have been built in five variants and they are in particularly widespread use in Italy. Variant 4 of the G 2000 BB, which was presented at the InnoTrans 2004 trade fair, and the similar Variant 5, for the Scandinavian market, are the most powerful diesel locomotives for use in Europe with a diesel engine producing an output of 2700 kW. Two further innovative features are a dynamic brake, rated at 2000 kW, and an exhaust particulate filter, which is unique for this power class. Practical tests have been carried out by both DB Systemtechnik (on the Frankenwald Ramp) and DB AutoZug GmbH and these have documented that the maximum tractive power currently available on diesel locomotives can be made to do its job effectively, making very good use of the available coefficient of friction, even with only four mechanically coupled wheelsets, in combination with an electronically controlled anti-slip system with a radar sensor. There is no difference in performance compared with modern electrical power-transmission systems.%Um wettbewerbsfähig zu sein, sind insbesondere kleinere Eisenbahnverkehrsunternehmen (EVU) gezwungen, den gesamten Transportweg eines Zuges einschließlich möglichst aller notwendigen Rangierarbeiten mit einer einzigen Lokomotive abzuwickeln. Vossloh Locomotives entwickelte ein Lokomotivkonzept, das diese Aufgabe erfüllen kann. Der nachfolgende Beitrag erläutert die Entwicklung einer dieser Anforderung gerecht werdenden Lokomotivplattform auf Basis der dieselhydraulischen Lokomotive G 2000 BB.
