Vossloh Locomotives is one of the European market leaders in the construction of diesel locomotives. These rail vehicles consistently set new standards in terms of efficiency, flexibility, and environmental friendliness for both mainline and shunting locomotives. The G 1000 BB is suitable for heavy shunting and light mainline service. It is approved for use in Germany, Italy, Luxembourg, and France. In SBB Cargo, they carry the series designation Am 842. Some locomotives were leased in 2006 by the then Railion Deutschland to test their suitability as a potential successor to the series 290/294. They were assigned the series number 261 for this purpose, but these officially recorded numbers were not marked on the vehicles.
