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 . 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.
