first full livery, Tornado would be fitted with an authentic rimless chimney, described as the original non-capped version. The fluted chimney was still not fitted at the time of its LNER Apple Green livery launch on 13 December 2008, due to it still being machined at the manufacturer. It was completed and fitted in time for the inaugural main line passenger run. The chimney was also fitted with a spark arrestor. Tornado has two whistles: a standard LNER "teapot" whistle on the cab front and an ex-LNER chime whistle from LNER Class A4 4482 Golden Eagle behind the right-hand deflector. Boiler from Meiningen Works Consideration of the boiler began in late 1998. No standard gauge boiler had been built in Britain for such a large express locomotive since the 1960s, and it was required to be based on the original LNER design but meet modern safety standards. Design changes included the cheaper modern-day fabrication method of a welded, rather than riveted, firebox and boiler tubing; the use of steel, rather than copper, for the firebox; and the aforementioned height reduction for Network Rail regulations. While manufacturing facilities still existed in Britain to manufacture such a large boiler, because of the design differences from the originals the trust required a supplier with specific experience of designing, building, and certification of modern steam engine boilers as required by the EU's Pressure Equipment Directive. In early 2002, the Deutsche Bahn's Meiningen Steam Locomotive Works in Germany was identified as a suitable supplier. It possessed the required knowledge as main line steam operation had continued in East Germany until the mid-1980s, 70% of its work still involved steam, and it still possessed the powerful plate roller machines. The trust did not have sufficient funding to place the order until January 2005. 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 at Meiningen. The fitting was not without incident though, as the extra weight caused some compaction of the trackbed, and assistance was required to move the locomotive back into the works, by a combination of being winched, towed by a forklift
