The overhaul required a new left-hand cylinder to be cast.<ref>SVR News 155, 160</ref> Work on the boiler at Pridham's in Devon involved building an almost complete inner firebox and replacing most of the outer box.<ref>SVR News 165</ref> The overhaul continued to make steady progress and was eventually completed in time for Taw Valley to re-enter service on 16 May 2015, hauling an incoming "British Pullman" rail tour consisting of 12 coaches and a Class 67 diesel from Bewdley to Bridgnorth,<ref>I. Walker, "Steam Locomotive Notes", ''SVR News'' 190 (2015) p. 28</ref> and an SVR service from Bridgnorth to Kidderminster. Taw Valley is the only SVR steam locomotive, apart from 600 Gordon, equipped to work with air braked rolling stock. However the locomotive is no longer registered to work on the main line (the owner sold [[Carriages formerly resident on the SVR|support coach 35479]] in 2015 around the time the locomotive re-entered service). It has also not began to [[SVR-based locomotives visiting other events|appeared appear at another railwayother railways]] since that timeonly from 2023.
