}}'''D182''' is a '''BR Class 46''' diesel electric locomotive. It arrived on the SVR in May 2022 for the Spring Diesel Festival and remained on hireuntil the November.

The BR Class 46 diesel-electric locomotive was originally classified as the Type 4 ‘Peak’and was the third of the Sulzer 'Peak' classes. The introduction of [[TOPS codes|TOPS]] saw the type designated as Class 46. A total of 56 were built by BR Derby between 1961 and 1963 as part of BR's modernisation plans to replace steam locomotives.

A total of 56 were The first Sulzer Type 4 class, which became the Class 44, was built by BR Derby between 1961 and 1963 as part 1959-60. All 10 members of BRthe class were named after mountains, giving rise to the nickname 'Peak's modernisation plans which carried over to replace steam locomotivesthe subsequent Class 45 (built 1960-62) and Class 46. It was the third <ref group="note">None of the ‘Peak’ subsequent 'Peak' classes were named after what became the Classes 44 mountains, although some Class 45s and 45one Class 46 were named after Army regiments.</ref> The Type 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.

They The members of the class were fitted all withdrawn between 1977 and 1984. One was subsequently destroyed in 1984 in a staged collision as part of a nuclear flask test, with steam powered train heating boilers all butthree being scrapped. Of the three surviving examples, unlike some of Pete Waterman's D172 (46035) became the Class 45s, never fitted with electric train supplyfirst 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 BR Blue livery with the full yellow cab front.<ref>[https://www.brdatabase.info/locoqry.php?action=locodata&type=D&id=182&loco=182 BR Database] (retrieved 19 August 2022)</ref>

D182 arrived on the SVR in May 2022 for the Spring Diesel Festival. In July 2022 the SVR announced that, given the then issues with coal supply, it had also taken the opportunity to retain the locomotive following the Spring Diesel Festivalon hire, to give providing another locomotive for use during the main season.<ref>[https://www.svrlive.com/bljul22 Branch Lines, July 2022]</ref> Its boiler meant a further period of hire, to cover winter services, was also mooted.

Unfortunately its first week In October 2022 a director of use saw 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 [[Diesel galas|Autumn diesel bash]]. If all goes to plan, the loco will return to the SVR next year ready to steam."''
