60163 Tornado is a main line coal-fired steam locomotive built in Darlington, County Durham, England. Completed in 2008, Tornado was the first such locomotive built in the United Kingdom since Evening Star, the last steam locomotive built by British Railways in 1960. It is the only example of an LNER Peppercorn Class A1 locomotive in existence, the entirety of the original production batch having been scrapped without preservation. The locomotive’s namesake is the Panavia Tornado, a combat aircraft flown by the Royal Air Force. In April 2017, Tornado became the first steam locomotive to officially reach 100 mph in over 50 years on British tracks.
Construction of Tornado began in 1994, and was at Darlington Works for most of the project, while numerous components such as the boiler were manufactured elsewhere. The project was financed through fundraising initiatives such as public donations and sponsorship deals; further funding came from hiring out Tornado itself for special rail services. Construction was completed in 2008, and full certification of the locomotive was achieved in January 2009. Having been designed with compliance to modern safety and certification standards, Tornado has been conducting passenger services on the UK rail network and on mainline-connected heritage railways since 2008.
