The G 2000 BB is a four axle heavy shunting and mainline locomotive, designed by German company Vossloh and built at the former MaK plant in Kiel.

The initial model had an asymmetric cab (see image) with a walkway; the asymmetric cab design allows the walkway to extend all the way to each end of the locomotive; coupled with remote control operation this means that shunting can be done from an external viewpoint whilst still riding on the locomotive.

This variant also included a hydrodynamic retarder (a type of braking system) as part of the Voith supplied transmission package.

The last variant is G 2000-5 BB which has the same upgrades as the fourth offering, it is designed for the Scandinavian market and as such has anti wheel slip technology, and can be equipped for service down to −40 °C (−40 °F).

[2] The locomotives are certified for use on the railways of Germany, Switzerland, Italy, Netherlands, Belgium, France, Sweden, Denmark and Poland.
