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[5]
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[6] due to their presence at times on the UK side of the channel tunnel. ECR assigned the codes FB1544 to FB1547 to these locomotives.[7][8][9][10]
