At the beginning of the 2000s, the Austrian Federal Railways ÖBB ordered 90 Class 2070 shunting locomotives from the Kiel MaK mechanical engineering department. Caterpillar's 12-cylinder diesel engine produces 738 kW at 2100 rpm. The top speed is 100 km/h. These locomotives, which maK refers to as type G 800 BB, are the basis of the manufacturer's 4th type program. The locomotive construction in Kiel was taken over by Vossloh and further developed. As a more powerful version of the G800, the G1000, equipped with an MTU eight-cylinder diesel engine, was launched on the same chassis. The 1100 kW (at 1860 rpm) and 100 km/h fast locomotive can be ordered for axle loads from 18 to 20 t and with country packages for right and left traffic. Between 2002 and 2016, Vossloh delivered 103 copies to railways in Germany, France, Italy, Luxembourg and Switzerland. Deutsche Bahn was also interested in the four-axle and rented locomotives from various landlords for several years. The locomotives reliably provided freight services in almost all federal states. The locomotives are used in heavy shunting service, but also in front of local freight trains. Some G1000 belong to locomotive rental companies such as Northrail in Germany or Ferrotract in France and are employed within the respective national borders, for example, in all sectors of medium-heavy local freight transport, but also in the factory traffic of large industrial enterprises or in sea and inland ports. Various owners such as Spitzke Logistik (D) or Colas Rail (F) use the reliable four-axle axles in construction train traffic. Even after delivery of the Voith Gravita, DB occasionally uses borrowed G1000 in the event of vehicle bottlenecks.
