The newly-built locomotive 6399 'Fury', of the London Midland and Scottish Railway, leaving the Hyde Park works in Glasgow for trials, 7th February 1930. The Fury was an experimental express passenger locomotive using a high pressure steam boiler system, which proved impractical and led to the locomotive being laid up until 1935. It was then rebuilt with a conventional boiler to become 6170 British Legion. Image colourized by David P. Williams. (Photo by S. R. Gaiger/Topical Press Agency/Hulton Archive/Getty Images)
