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.
Contents
Design and construction
The class was designed at the ex-LNER works at Doncaster which was also responsible for building 25 of the 115-strong class. The remaining 90 were split between Horwich and Derby Works.
The last in the series, No.76114, was also the final steam engine to be constructed at the 'Plant' (as Doncaster works was known). 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 5-foot-3-inch (1.600 m) 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.[1]
Operation
With its 5-foot-3-inch (1.60 m) diameter driving wheels this sixth of the BR standard designs was clearly biased towards freight working. An axle-loading of only 16 long tons 15 cwt (37,500 lb or 17 t) meant its route availability was virtually unrestricted. Batches were allocated to every BR region except the Western.
Scottish Region
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.
Southern Region
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 2-6-0 or 4-4-0 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 S.W. 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.
North Eastern Region
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.
London Midland Region
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.
Eastern Region
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. 76079 has visited the North Norfolk Railway in preservation times.

- 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.[2]
Preservation
Lua error in package.lua at line 80: module 'strict' not found. Four examples have been saved:
- 76017 - Is on the Watercress Line and is currently under overhaul.
- 76077 - Is being restored on the Gloucestershire Warwickshire Railway.
- 76079 - Formerly owned by Ian Riley, now based at the NYMR. The locomotive has recently returned to traffic following an overhaul, Mainline Certified. Boiler ticket expires 2024.
- 76084 - Owned by 76084 Locomotive Company Limited. Currently on North Norfolk Railway for 2013, 2014 and 2015 seasons. Planned to go on main line by early 2016 - support coach (BSK 35457) already refurbished for the purpose.
Of the 4 to be preserved all but 76077 have steamed in preservation and of the 3 that have run only 76079 has operated on the main line, its main career on the main line was when it was owned by Ian Riley in Bury, Lancashire when it would sometimes be seen double heading trains with another of Ian Riley's locomotives no 45407 The Lancashire Fusilier. It even worked "The Cambrian" trains from 2006 till 2009, these were trips run from Machynlleth to Porthmadog (Extended to Pwllheli from 2008 on Wed & Fri). It was eventually sold from Ian Riley to the NYMR and after completion of its recent overhaul it once again has a main line certificate but is restricted between Battersby and Whitby on the Esk Valley Line.
According to Steam Railway Magazine, 76077 was originally preserved with the intention of recreating a BR 3MT 2-6-0, which shares the same bottom end as the 4MT, though different wheel types (albeit same size), the boiler would have come from a GWR 5105 "Prairie" tank loco, which was also earmarked, but in the end, both were preserved as built, as the funding was not available for the purchase of both by one group.
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.[3]
Bachmann produces a ready-to-run model in both 00 and N gauge.[4]
