Under the earlier BR classification system, the type was given the designation AL6 (meaning the sixth design of AC locomotive) and locomotives were numbered E3101–E3200. In 1968, this was changed to Class 86 when British Rail introduced the TOPS classification system.

2024年7月11日 · The AL6 design was produced ostensibly from the experience gained with the first five designs in the early years of the WCML electrification. It featured a general construction design and bogies closely following those of the AL5, high-tension tap changing (power control) pioneered on the AL2 and a completely modular interior based around the ...

2024年7月22日 · British Rail at Doncaster Works, along with English Electric at their Vulcan Foundry works would produce a standard production AC Locomotive which would be called the AL6. The AL6 was very similar to the prototype locomotives taking design elements such as the general construction of the bodies and bogies and control systems.

The Class 86 AL6 was the production class of AC electrics built for the West Coast Main Line following on from the pilot-scheme AL1-5 (Classes 81 to 85). The AL6 took advantage of experience gained from the earlier locomotives including the fitting of only one pantograph and with changes to equipment.

The loco was constructed as an AL6 at Doncaster Works, new to traffic in August 1965 numbered E3103. It was renumbered to 86004 in June 1973, renumbered again to 86404 in January 1986 and finally to 86604 in September 1990.

BR AL6 AC electric loco E3135 at Euston station, in 1966. The loco had entered service in January 1966, and later became Class 86 86040, and later 86256. It was withdrawn in October 2002, and finally scrapped in March 2006.

2020年4月21日 · Originally designed as AL6 locos and numbered E3101-E3200 but with British Rail starting to use the TOPS (Total Operations Processing System) in the early 1970s they were all classified as class 86 with various sub classes to denote various modifications over the years to gearing, suspension and heating.
