LNER Class A4
The Class A4 is a class of streamlined 4-6-2 steam locomotive designed by Nigel Gresley for the London and North Eastern Railway in 1935. Their streamlined design gave them high-speed capability as well as making them instantly recognisable, and one of the class, 4468 "Mallard", holds the world record as the fastest steam locomotive. Thirty-five of the class were built to haul express passenger trains on the East Coast Main Line route from London Kings Cross via York to Newcastle, and later via Newcastle to Edinburgh, Scotland. They remained in service on the East Coast Main Line until the early 1960s when they were replaced by Deltic diesel locomotives. Several A4s saw out their remaining days until 1966 in Scotland, particularly on the Aberdeen - Glasgow express trains, for which they were used to improve the timing from 3.5 to 3 hours.
LNER Peppercorn Class A1 60163 Tornado
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.
