GB Railfreight's latest order with EMD is in addition to the eight class 66 locomotives which it ordered in September 2013, and brings its total investment to around £50m. The acquisitions will expand the operator's class 66 fleet to 71 when the new locomotives arrive later this year.

The class 92 locomotives are being acquired from GB Railfreight's parent company Europorte, which is a subsidiary of Channel Tunnel concessionaire Eurotunnel. The electric locomotives will allow GB Railfreight to start operating trains through the Channel Tunnel.
