}}'''80079 ''' is a '''BR Standard Class 4 2-6-4T ''' tank engine designed by R.A. Riddles. The Class 4 tank engine was derived from the ex-LMS Fairburn 2-6-4T, and was used mainly on commuter and outer suburban services. A total of 155 were built, of which 15 have survived into preservation. They had a BR route availability classification of RA5; when used on BR Western Region running lines such as the Severn Valley branch this equated to a [[GWR Power and Weight Classification|Blue route availability]].<ref>British Railways Western Region, Locomotive Route Availability, June 1963</ref>

In December 1981 filming took place for an episode of [[List of film and TV productions filmed on the Severn Valley Railway#TV Commercials and other | ITV’s ''Game for a Laugh'']]. This featured musician and entertainer Joe Brown firing 80079, a job he previously did for BR while a fireman at Plaistow.
In early 1987 work was carried out on the boiler in an attempt to extend the 'ten year ticket' for a further three years.<ref>SVR News 83</ref> This was partially achieved, with 80079 being withdrawn due to loose/thin flue tube ends in early 1989.<ref>SVR News 92</ref> Apart from the boiler, the locomotive was considered in good condition mechanically, so when an overhaul began in 1990 the work mainly comprised new bunker platework, new pipework, reconditioned cab fittings and repairs to the tanks.<ref>SVR News 98</ref> Some attention was also required to the frame.<ref>SVR News 105</ref> In spring 1991 an [[:Category:SVR fundraising lotteries|SVRA Birmingham Branch raffle]] helped raise funds for the boiler work.<ref>SVR News 98/99</ref>
80079 returned to service in May 1993, making an early appearance on the Central Wales main line before spending the summer at the Llangollen Railway.<ref>SVR News 106-107</ref> During the second ticket the locomotive was a consistent performer and in 2000 recorded 12,849 miles, the highest mileage of any SVR locomotive in any single year between 1967 and 2004. The locomotive finally succumbed to tube failure in summer 2002, shortly before the 'ten year certificate' expiry date.<ref>SVR News 140</ref>

After cosmetic restorationat Bridgnorth, 80079 was temporarily placed on display at the [[National Railway Museum | NRM Shildon]] in March 2005.<ref>SVR News 150</ref> It was then one of the first batch of locomotives to be displayed in [[The Engine House]] at [[Severn Valley Railway Timeline 2000-2009#2008 | opening in 2008]]. It has remained on display there since, although it has occasionally been shunted outside to be re-positioned or turned on [[Kidderminster Turntable]] (locomotives at either end of the Engine House generally face towards the centre as seen below). <gallery mode=packed heights=200px style="text-align:left">80079_20090822.jpg|80079 in 2009 after entry in 2008, facing south80079_20110305.jpg|80079 in March 2011 after being moved80079_20110527.jpg|80079 in May 2011 after being turned to face north80079_20120708.jpg|80079 in July 2012 after being moved</gallery> {{As of|20172024}}, it remains on display there80079 has been turned to face south again and is back in the 2008 location. 80079 The locomotive is owned by The [[Passenger Tank Fund]].
