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.
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.[1] 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 5feet 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.[2] Rectangular type coupling rods rather than the original fluted type, were fitted to 76035 onwards.[3]
With its 5feet diameter driving wheels this sixth of the BR standard designs was clearly biased towards freight working. An axle-loading of only meant its route availability was virtually unrestricted. Batches were allocated to every BR region except the Western.[4]
The Eastern Region divided its 15 between two London depots. Five went to Stratford on the ex-Great Eastern section, and the remainder to the one-time Great Central depot at Neasden. Made redundant by dieselisation the Stratford engines were transferred to the Southern and arrived at Brighton. The Neasden engines also in due course departed the capital, in this case for Chester and ex-Cambrian Railways territory. One Eastern locomotive was 76034 which was fitted with a tablet catcher for running over the M&GN lines in East Anglia.
Apart from a pair allocated to Leicester, most of the London Midland Region's batch of 15 spent their working lives in the Liverpool, Manchester and Preston areas. Some were allocated to the Nottingham area, and took over the working of the afternoon 16:45 fish train ex Grimsby from 4F 0-6-0s.
At first the North Eastern Region scattered its 13-strong allocation far and wide: Darlington, Gateshead, Hull, Sunderland and York. Later all were concentrated at either Kirkby Stephen or West Auckland to work over the Stainmore route whose viaducts had severe weight restrictions. Like their small cousins the 2MT 2-6-0 class the Moguls were ideal for working the line. They worked coal trains as well as passenger services and were a regular choice for excursions from Tyneside to the Lancashire coast resorts.
Thirty-five units were allocated to the Scottish Region, used on the Waverley Line between Carlisle and Hawick. Others appeared on the 'Port Road' from Dumfries to Stranraer. The Scottish examples were mainly concentrated in Ayrshire and around Glasgow, and at one time Corkerhill depot was home to ten of the class. Five units were based in Aberdeen and three went to Thornton in Fife.
The Southern moguls (originally 37) were also concentrated in one area around Eastleigh, Southampton and Bournemouth. They were used between Portsmouth, Salisbury and Cardiff, Reading to Redhill, Brighton to Bournemouth and over the Swanage branch. Their most celebrated duty was the London Waterloo to Lymington boat train. However this had nothing to do with the engines' capabilities; it was simply that among tender engines only a or could fit on the turntable at Brockenhurst. In the last few years of steam operation on the 'Southern' a few examples were allocated to Guildford shed before moving on to Feltham shed in south-west London.
All 17 locomotives equipped with the BR1B high-sided tender were allocated to the Southern Region. The BR1B tender had a higher axle load than the locomotives.

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.[6]
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.

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.[12]
Bachmann produces a ready-to-run model in both OO[13] [14] and as part of their Graham Farish range for British N gauge.[15]
