The British Rail Class 86 was the standard electric locomotive built in the 1960's. 100 of these locomotives were built from 1965 to 1966 at either English Electric at their Vulcan Foundry Works at Newton-le-Willows in Lancashire, or the Doncaster Works. Orginally, they were built to haul trains on the then newly electrified West Coast Mainline from London Euston to the West Midlands and the North West, with Preston and Glasgow Central following later on. Under the early classification system, they were designated AL6 (meaning the 6th design of an AC locomotive) and they were numbered E3101 - E3200. When British Rail introduced the TOPS classification system, they were designated Class 86.
