Template:Short description Template:Use dmy dates Template:Use British English Template:Multiple issues Template:Infobox locomotive The BR Standard Class 4 2-6-0 is a class of steam locomotive designed by Robert Riddles for British Railways (BR). 115 locomotives were built to this standard.

Design and construction

The class was designed at the ex-LNER works at Doncaster which was also responsible for building 70 of the 115-strong class. The remaining 45 were built at Horwich.<ref name="RCTS">Template:Cite book</ref> None were built at Derby Works although it was intended that 20 would be built there, Doncaster in fact took them on.

The last in the series, No.76114, was also the final steam engine to be constructed at the 'Plant' (as Doncaster works was known). 76099 was last steam locomotive to be built at Horwich and in fact, was the last of the class to be completed, just after 76114 at Doncaster. The Standard Four Mogul was essentially a standardised version of the LMS Ivatt Class 4, and was primarily intended for freight use.

Although a BR Standard, the 4 2-6-0 class did not have the same design of wheels as the Swindon-built 82XXX and 77XXX Class 3 engines which also had Template:Convert driving wheels, yet all three locomotive classes share the same cylinder casting.

The cylinder covers of engines built early in the programme of construction were fitted with "screw-in" type pressure relief valves. From September 1955 revised cylinder covers were introduced for renewals incorporating "bolt-on" type pressure relief valves.Template:Efn Rectangular type coupling rods rather than the original fluted type, were fitted to 76035 onwards.<ref name="RCTS"/>

Operation

With its Template:Convert diameter driving wheels this sixth of the BR standard designs was clearly biased towards freight working. An axle-loading of only Template:TonCwt to t meant its route availability was virtually unrestricted. Batches were allocated to every BR region except the Western.<ref>Template:Cite web</ref>

Accidents and incidents

  • On 23 September 1954, locomotive No. 76017 was hauling a freight train that overran signals and was derailed by trap points at Template:Rws station, Hampshire.<ref name="Bishop">Template:Cite book</ref>
  • In December 1957, locomotive No. 76016 was hauling a freight train that overran signals and was derailed by trap points at Template:Rws station, Hampshire.<ref name="Bishop"/>
  • On 12 February 1960, locomotive No. 76026 was hauling a freight train that overran signals and was derailed by trap points at Whitchurch Town station.<ref name="Bishop"/>

Preservation

Four engines have survived into preservation, all four built at Horwich Works and rescued from Woodham Brothers scrapyard at Barry Island. Three members of the class have steamed so far in preservation but 76077 has yet to do so and is at present undergoing restoration from scrapyard condition. As of September 2023, no members of the class are mainline certified. All three engines that have run in preservation have been on the main line, but only two have hauled railtours, 76079 and 76084. On 13 October 2022, 76017 was moved by rail from its home at the Watercress Line to the Bluebell Railway.<ref>Template:Cite web</ref>

76079's main career on the main line was when it was owned by Ian Riley in Bury, Lancashire, but it was eventually sold to the NYMR. After completion of its most recent overhaul in 2014 it once again had a mainline certificate but was restricted between Battersby and Whitby on the Esk Valley Line. 76084 meanwhile, was certified to operate over the national network hauling railtours alongside passenger runs along the Bittern Line and the Esk Valley Line.Template:Cn

Models

The erstwhile Kitmaster company produced an unpowered polystyrene injection moulded model kit for 00 gauge. In late 1962, the Kitmaster brand was sold by its parent company (Rosebud Dolls) to Airfix, who transferred the moulding tools to their own factory; they re-introduced some of the former Kitmaster range, including this locomotive. In time, the moulding tools passed on to Dapol who have also produced the model kit.<ref>Template:Cite book</ref>

Bachmann produces a ready-to-run model in both OO<ref>Template:Cite magazine</ref><ref>Template:Cite magazine</ref> and as part of their Graham Farish range for British N gauge.<ref>Template:Cite web</ref>
