LNER Peppercorn Class A1 No. 60163 Tornado is a 4-6-2 steam locomotive completed in 2008 to an original design by Arthur Peppercorn. It is the first new build British mainline steam locomotive since 1960, and the only Peppercorn Class A1 in existence after the original batch were scrapped. In 2017, Tornado became the first steam locomotive to officially reach 100 mph (160 km/h) on British tracks in over 50 years.

After the project was founded by the A1 Steam Locomotive Trust in 1990, construction of Tornado began in 1994 and mostly took place at Darlington Works, with other components manufactured elsewhere. The project was financed through fundraising initiatives, public donations, sponsorship deals, and hiring out Tornado itself for special services. The locomotive was granted its mainline certificate in January 2009, having been designed in compliance with modern safety and certification standards.

The locomotive worked on heritage and mainline trains across Britain between 2008 and 2022, when it was withdrawn for overhaul.[2] It returned to operation in August 2024 following setbacks from overhaul.[3]
