The Class 70 diesel locomotive (the original Class 70 was an early DC electric locomotive) is the most powerful freight diesel locomotive on British rails today with nearly 3,700hp to play with and the first General Electric traction built for the UK [1]. Over thirty have been bought by Freightliner and Colas Rail, they are used on intermodal and heavy haul freight services.

The Class 70 had a troublesome entry into service with a very poor availability rate in its early days on British metals and a number of fires. One locomotive (70 012) was very bad damaged during a mishap during unloading from a cargo ship at Newport Docks and had to be returned to the US [2]. Nowadays the locomotives are much more reliable.

The original twenty Freightliner locomotives are known as the 70/0 with the ten Colas Rail locomotives 70/8. Seven more Class 70s were later ordered for Colas for delivery in 2017.
