The Class 86 was British Rail's standard electric locomotive design in the 1960s. A total of 100 were built to haul trains along the newly electrified West Coast Mainline and aided in the replacement of many steam locomotives. The class was a result of experience learned from the classes 81 through 85, which were all essentially testbeds for locomotive development. The 86 retained many of the best features from these locomotives albeit with some of its own unique design features. The class saw much development over its lifespan with many locomotives overhauled and modified for different purposes, resulting in a wide selection of different subclasses. As well as being used on top level express passenger services, the class have also been frequently used for heavy freight services and still can be seen in use today for this purpose. A few of the class are still used for charter services, while 3 have also been preserved. Many were exported for use in Eastern Europe, with a number of examples also being scrapped since the mid-1990s.
