It was promptly 'red carded', although this was briefly rescinded to enable it to act as an additional water carrier for [[Severn Valley Railway Stock Book Ninth EditionTimeline 2010-2019#2015|that winter's major infrastructure project]], initiated by Severn Trent Water, which involved replacing three of the four large diameter water pipes bringing water from the Elan Valley to Birmingham where they cross under the trackbed between Bewdley and Arley near [[Folly Point]]. The main picture (top right) shows 431 at [[Bewdley]] in March 2015 having returned, but still awaiting attention. At that time the Wagon Department noted that "''It is now back with us, while we look for the best way to proceed. The worst case is replacement of all four buffers with reconditioned units, which will eat heavily into this year's budget. Once this work starts, paintwork will also be attended to''."<brref>SVR News 191</ref> The picture below shows 431 at Highley in October 2018, with the paintwork still requiring attention. Traces of its later number TEX 47881 can still be made out at the nearer end of the tank. <gallery mode=packed heights=200px style="text-align:left">PO_431_20181020.jpg|431 at Highley in 2018 </gallery> During 2019 sister wagon [[Regent Oil & Texaco 345 Aviation Fuel Tank Wagon|345]] was similarly 'red carded' for a faulty Oleo buffer and moved in to Bewdley Down Yard for repair. While there, the opportunity was taken to repaint it in Regent livery. However {{as of|2022|lc="y"}}, 431 is still awaiting similar treatment.  431 is owned by [[SVR(H)]]. ==See also==*[[Goods Wagons | List of goods wagons]]*[[Regent Oil & Texaco 345 Aviation Fuel Tank Wagon]]*[[Leapgate Private Sidings | Leapgate Private Sidings, owned by Regent/Texaco]] ==References==
