On 16 July 2006 the boiler arrived by sea and was unloaded at Darlington with a 200-ton crane, having taken just nine months to build. The fitting of the 21-ton firebox and boiler unit to the wheeled locomotive frame was said to have been a perfect fit, requiring no grinding at all, a tribute to the accuracy of the design and construction by the Meiningen works. The fitting was not without incident though, as the extra weight caused some compaction of the track bed, and assistance was required to move the locomotive back into the works, by a combination of being winched, towed by a forklift truck and pushed with Land Rovers.
