BRBritish Rail or British Railways Class 46
The BRBritish Rail or British Railways Class 46 diesel-electric locomotive was originally classified as the Type 4The British Railways classification for diesel locomotives of 2000 bhp to 2999 bhp and was the third of the Sulzer 'Peak' classes. The introduction of TOPS saw the type designated as Class 46. A total of 56 were built by BRBritish Rail or British Railways Derby between 1961 and 1963 as part of BRBritish Rail or British Railways's modernisation plans to replace steam locomotives.
The first Sulzer Type 4The British Railways classification for diesel locomotives of 2000 bhp to 2999 bhp class, which became the Class 44, was built between 1959-60. All 10 members of the class were named after mountains, giving rise to the nickname 'Peak' which carried over to the subsequent Class 45 (built 1960-62) and Class 46.[note 1] The Class 46 were built with the same Sulzer 12-cylinder 12LDA28-B engine as the Class 45s, rated at 2,500 bhp, but with Brush transmissions. This arrangement was later developed further with the ubiquitous Class 47.
The class were used on both goods and passenger services, with the latter notably including heavy cross-country expresses between the north east and south west. They were fitted with steam powered train heating boilers but, unlike some of the Class 45s, never fitted with electric train supply.
The members of the class were all withdrawn between 1977 and 1984. One was subsequently destroyed in 1984 in a staged collision as part of a nuclear flask test, with all but three being scrapped. Of the three surviving examples, Pete Waterman's D172 (46035) became the first preserved diesel locomotive to receive mainline certification in 1994.
D182 entered service in September 1962 at Gateshead, where it remained allocated for its entire service career. As built, it was fitted with vacuum brakes and steam heat. It was converted to dual braking in August 1970 by the addition of air braking. By that time it carried BRBritish Rail or British Railways Blue livery with the full yellow cab front.
The introduction of TOPSTotal Operations Processing System, an American computer system adopted by BR from the late 1960s to number and manage rolling stock. saw the locomotive renumbered as 46045 in October 1973.
During 1984 the locomotive was 'stopped' on numerous occasions with traction motor and other power issues. After the locomotive failed at Taunton on 24 November 1984 while hauling the 07.50 Bristol to Penzance service, it was withdrawn and returned to Derby.
Research department use
On withdrawal it was renumbered 97404 and transferred to Research department stock during December 1984, running until 1986 when it was stored after suffering a generator flashover. It remained in DepartmentalRolling stock used for the railway’s own functions (engineering etc.) rather than for general passenger or goods traffic. stock until September 1990.
D182 is owned by Peak Locomotive Company Limited and is normally based at the Midland Railway Centre, Butterley. It retains its steam heating boiler.
The locomotive has carried several different liveries in preservation. The first picture below shows D182 in 2008 at Grosmont on the NYMR, then in BRBritish Rail or British Railways green livery. The second picture shows D182 in 2016 at Butterley in BRBritish Rail or British Railways livery with half yellow cab front.
D182 subsequently underwent an overhaul, with the overhauled generator, turbocharger and intercoolers being refitted in October 2020.. Since that overhaul the locomotive is now in BRBritish Rail or British Railways blue livery with full yellow cab front.
SVRSevern Valley Railway use
D182 arrived on the SVRSevern Valley Railway in May 2022 for the Spring Diesel Festival. In July 2022 the SVRSevern Valley Railway announced that, given the then issues with coal supply, it had also taken the opportunity to retain the locomotive on hire, providing another locomotive for use during the main season. Its boiler meant a further period of hire, to cover winter services, was also mooted.
In October 2022 a director of the owners announced on Facebook: "In the coming weeks, the loco will return to the Midland Railway for the overhauled steam heating boiler to be installed and commissioned. Several other repairs will also be made including to the cooling system which caused the loco to fail at the Autumn diesel bash. If all goes to plan, the loco will return to the SVRSevern Valley Railway next year ready to steam." It left the SVRSevern Valley Railway on 3 November.
