Riddles. The Standard 4MT was designed for mixed traffic use on secondary routes where the BR Standard Class 5 and its predecessor, the ‘Black Five’, would be too heavy.
==75069 in service==
75069 was one of the final batch allocated to the BR Southern Region, which were built with a larger tender giving greater coal and water capacity but with the same route restrictions as the Standard Class 5.

75069 arrived on the SVR from [[Barry Scrapyard]] on 31 March 1973. A Fund raising was helped by a [[:Category:SVR fundraising lotteries|raffle organised by the SVRA Birmingham Branch]] in 1973,<ref>SVR News 30</ref> and a further raffle to help fund the restoration and boiler re-tube in 1978.<ref>SVR News 47</ref> In 1983 another [[:Category:SVR fundraising lotteries| raffle organised by the SVRA Birmingham Branch]] was held to raise funds for superheater elements.<ref>SVR News 66, 67</ref> The restoration lasting which lasted more than 11 years was completed just in time for the locomotive, still in undercoat, to take part in the September 1984 Enthusiasts’ Weekend.<ref>SVR News 74</ref>
In addition to service on the SVR during the following 10 years, 75069 also made a number of [[The Severn Valley Railway on the main line | appearances on the main line]]. In 1987 the locomotive was due to work a full Cardigan Bay Express season along with [[GWR 7819 Hinton Manor | 7819 Hinton Manor]], but was unable to complete this due to a crack in the back left hand flange of the firebox.<ref>SVR News 85</ref> [[LMS Ivatt Class 2 46443 | 'Mickey Mouse' 46443]] was sent to Machynlleth to deputise and proved a worthy replacement.

After a lengthy period in storage, hopes of a return to service were raised in early 2009 when work was carried out to assess the condition of the boiler. However this assessment revealed that significant work would be required<ref>SVR News 168</ref> and [[GWR Pannier 1501 | 1501]], seen as a potential quick turnaround, was selected for overhaul instead.<ref>SVR News 169</ref> 75069’s overhaul Heavy General repair finally began in early 2013<ref>SVR News 180</ref> : the boiler barrel and {{As much of|the firebox was entirely new and many of the fittings and almost all of the pipework were replaced. A new cab, new smokebox and chimney, replacement steelwork in the tender coal space and new drag box were among other major repairs. Work cost over £900,000 and involved more than 25,000 man hours of effort.<ref>Express Points, January 2019</ref><ref>[https://www.bbc.co.uk/news/av/uk-england-47237824/men-rebuild-steam-engine-for-severn-valley-railway BBC News 15 February 2019] (Retrieved 16 February 2019)</ref> Although initially advertised as returning to traffic prior to both the 2017|lc=y}}, progress on this continues at and 2018 [[Bridgnorth Loco WorksAutumn Steam Gala]]s, the locomotive's first test runs started 11 December 2018 with her boiler exam two days later.<ref>The Railway Magazine, January 2019, p.66</ref> She returned to traffic 16 February 2019 at the start of the season's services.
One major task that has already been completed is that of complete replacement In the early morning of 22 July 2019, 75069 collided with a [[Tales from the dragboxSevern Valley#Minor_Derailments|fallen tree]] between [[Hampton Loade]] and [[Country Park Halt]] while running light engine from Bridgnorth to work a service train from Kidderminster. AdditionallyThe locomotive’s bogie was derailed and although the bogie axles were found not to have been bent, during dismantlement a number of front end fittings were damaged including the cylinders the flange of one of the rear guard irons, steam heat and vacuum pipes, and a cylinder covers was found drain cock casting and drain pipe.<ref>Steam Railway Magazine Issue 496, p 13, ''Severn Valley '4MT' derailed after hitting tree'', statement attributed to be broken[[Severn Valley Railway Engineering Services|ESMP]] Manager Neil Taylor.
