The Vossloh G1206 is a B'B' diesel hydraulic freight locomotive built in Kiel and used by several European railway operators including a SNCF specific variant the BB 461000 series.
The design was created in the mid-1990s by Maschinenbau Kiel (MaK) for German coal supplier RAG Aktiengesellschaft and is a follow-on to the MaK G1205 locomotive class built as the SNCB Class 77. Production continued under Vossloh ownership of the Kiel plant
In 2007 a shunting specific variant, the G1206-2 was created and began production.
Four Caterpillar-engined locomotives hired from Angel Trains Cargo by Euro Cargo Rail were assigned to TOPS Class 21 due to their presence at times on the UK side of the channel tunnel. ECR assigned the codes FB1544 to FB1547 to these locomotives.
