Changes

Progress on the overhaul saw work on the locomotive's rear bogie truck completed, and work on the chassis. By early 2018 the boiler boiler was largely complete (and awaiting assembly), with a great deal of new material incorporated including new barrel, firebox outer wrapper skirts, all new stays, new longitudinal and palm stays, overhauled dome, new smokebox and new internal components such as the J pipe also being replaced.<ref>SVR News No. 199 and 200, Autumn and Winter 2017</ref> New tanks have been were completed at Dinas and await movement to Bridgnorth to add to a growing assembly of locomotive parts.

When Beamish bought the locomotive they could see some cracks in a small number of spokes. Once these were stripped at Bridgnorth, a great deal more cracks were revealed, to the extent that an independent inspection was commissioned using the magnetic particle inspection technique. The renewal of all four ‘driving’ wheels (coupled wheels) was instigated in 2018, the crank axle being retained, whilst the rest (wheel centres, tyres, front axle and crankpins) will be entirely new and are being prepared manufactured at South Devon Engineering.

A new cylinder block was commissioned and cast in 2014, however issues require required remedial attention. {{As of|By March 2019|03}} the reworked block is was awaited, before rewheeling can could commence.<ref>SVR News 205</ref>. Otherwise the The project is had been making slow but steady progress, with parts being reassembled, until being placed on hold in March 2020 due to the [[2020 coronavirus disease (COVID-19) pandemic|Coronavirus pandemic]].  In May 2021 Beamish Museum announced they had received a grant of £150,000 to complete the work and was waiting for the SVR to allocate it a place in their workstream. The work to this point had been chassis-focussed, with the aim being to install the new cylinder block and wheel Dunrobin, before completing the boiler (which was nearly finished) and final assembly.<ref>[http://beamishtransportonline. co.uk/2021/05/dunrobin-ten-years-on/ Beamish Transport Online blog, ''DUNROBIN – TEN YEARS ON'', Paul Jarman, 19 May 2021]</ref> Work recommenced at Bridgnorth in Autumn 2022 with some smaller works, and Dunrobin to enter the workshops at Bridgnorth with a re-start on its rebuild imminent.<ref>[http://beamishtransportonline.co.uk/2022/10/ti-news-24-2022/ Beamish Transport Online blog 22 October 2022] (Retrieved 2 November 2022)</ref> [http://beamishtransportonline.co.uk/category/dunrobin/ Beamish Transport Online blog] has regular updates on progress of the work.
