60163 Tornado is a mainline coal fired steam locomotive built in Darlington, 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. As of April 2017, Tornado became the first steam locomotive to officially reach 100mph in over 50 years on British tracks.
Construction of Tornado began in 1994, and was based 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.
The locomotive was built by the A1 Steam Locomotive Trust, a charitable trust founded in 1990 to build Tornado and possibly further locomotives. Tornado was conceived as an evolution of the LNER Peppercorn Class A1, incorporating improvements that would have been likely had steam continued, and changes for cost, safety, manufacturing and operational benefits, while replicating the original design's sound and appearance. Tornado, completely new-built, is considered the 50th Peppercorn A1, numbered next in the class after 60162, Saint Johnstoun, built in 1949.
