British Rail Class 83
class of 15 electric locomotives
The British Rail Class 83 electric locomotives were built by English Electric at Vulcan Foundry, in Newton-le-Willows, Merseyside, England, to haul services on the West Coast Main Line following its electrification.
History
Construction
Fifteen locomotives of Class 83 were built between 1960 and 1962 by English Electric at Vulcan Foundry, as part of British Rail's policy to develop a standard electric locomotive. Five prototype classes (81-85) were built and evaluated, which eventually led to the development of the Class 86 locomotive.
Three of these locomotives were to have been built as Type B, geared for freight trains; only two were so built, becoming E3303 and E3304. The third Type B, E3305, was never built as such; instead it was used as a test bed with silicon rectifiers and transductors, this being the first step towards thyristor control. It became a Type A, geared for passenger trains, and numbered E3100.
The other two Type B locomotives were eventually rebuilt as Type A, being renumbered E3098 (ex-E3303) and E3099 (ex-E3304). Power was provided by overhead catenary energised at 25,000 V AC.
Under the pre-TOPS British Rail classification, the first fourteen locomotives, E3024-E3035 and E3303, E3304 (later E3098 and E3099) were Class AL3 (meaning the third design of AC locomotive); the fifteenth engine, E3100, became Class AL3/1. All fifteen were included in the TOPS numbering system, being renumbered 83001-015.
The Polish EU06 class was produced by English Electric to a similar external design at the same time.

Why this record matters
“British Rail Class 83” is worth following because a concise public description often conceals a longer documentary argument. Here, British, Rail and Class provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 14, 2026. The linked authority identifier is Q4970855. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1960 and 1962.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
