}}83831 is one of thousands of 20 ton Coal Wagons coal wagons used by the GWR's Locomotive Department which were a common sight on the coal stages at GWR loco sheds; many were also hired out to collieries to replace elderly wooden-framed wagons. Locomotive Department wagons were identified by a large 'LOCO' painted on the sides, although 'LOCO' did not appear in the GWR list of [[Telegraph codes|telegraph codes]].

83831 was built at Swindon circa 1931-32 to Diagram N27, Lot 1084. When originally constructed at Swindon this vehicle was fitted with GWR DClll ratchet brakes (later replaced - probably by B.R. - with Morton lever brakes).<ref>[https://www.facebook.com/photo?fbid=1225671721205109&set=a.147151429057149 Goss P., Facebook, 21 June 2021] (Retrieved 26 June 2021)</ref> It was later sold by BR(W) to the CEGB for use at the Carmarthen Bay Power Station, numbered CB 66<ref>Railway Heritage Wagon Survey</ref>.

In spring 2004 83831 returned to the [[Wagon Department ]] for a repaint and what was anticipated to be minor repairs to the wagon floor.<ref>SVR News 147</ref> Further investigation revealed that subsequent use, including storing coal, loco ash and also rubble from the rebuilding of Highley platform, had reduced the original 6mm steel floor to a thickness of only 1mm in places. A new floor was therefore fitted for a second time in preservation, with completion of the overhaul and painting coinciding with the 2005 Autumn Steam Gala.<ref>SVR News 152</ref>It was subsequently used to store drums of cable for the S&T department. In June 2021 it was moved outside [[Bewdley Goods Shed]] for work by the Wagon Department on its leaf springs.

83831 is now principally used in the [[Demonstration Goods Train]].
