Changes

In 1870 the 3rd Duke of Sutherland financed the extension of the Highland Railway line from Golspie to Helmsdale via his own Dunrobin Castle. In return he received his own private station for his castle (still in use today as a public station on the line from Inverness to Thurso). He also received the powers to run his own train on the lines owned by the Highland Railway. He had his own carriages and locomotive built for the purpose. Dunrobin is an 0-4-4T, built by Sharp Stewart & Co of Glasgow in 1895 for to order number E1056. One of the unique features was the enlarged footplate and enclosed cab with a 4 person upholstered seat set high up at the Duke of Sutherlandback. It was used until around 1920 to pull the Duke’s private train between Dunrobin Castle and Inverness. In 1949, the Duke having acquired running rights on new British Railways revoked the Highland Railway as a condition of financing construction of part powers of the lineDuke to travel in his own train.<ref>[https://nationalrailwaymuseum.wordpress.com/2014/05/28/dunrobin-royal-engine/ Valkoinen, C., 'Dunrobin – The Little Royal Engine', National Railway Museum, 28 May 2014] Retrieved 15 August 2018</ref>

Dunrobin and a saloon were sold in 1950 to the Romney, Hythe and Dymchurch Railway. The locomotive ran large parts of the 700+ mile journey under its own steam. The locomotive was exported to Canada in 1965, but acquired in January 2011 by the Beamish Living Museum of the North<ref>[http://www.beamish.org.uk/beamish-buys-dunrobin/ Beamish announcement]</ref> and repatriated to the UK. On arrival, Dunrobin was brought to Bridgnorth on 19 May 2011 to be dismantled and the feasibility of restoration to working order assessed. Contracts were subsequently let to [[Severn Valley Railway Engineering Services]] for boiler and mechanical overhaul at [[Bridgnorth Loco Works]].

Progress on the overhaul saw work on the locomotive's rear bogie truck completed, and work on the chassis. A new cylinder block was commissioned. {{As of|By early 2018|03}} 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. A test steaming may be possible in 2018.<ref>SVR News No. 199 and 200, Autumn and Winter 2017</ref>  When Beamish bought the locomotive they could see some cracks in a small number of spokes. Once these New tanks were stripped completed 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, the crank axle being retained, whilst the rest (wheel centres, tyres, front axle and crankpins) will be entirely new. [http://beamishtransportonline.co.uk/category/dunrobin/ Beamish Transport Online blog] has regular updates on progress of the work which has necessitated many new parts including cylinder block, smokebox and boiler barrel sectionsDinas.
