High Pressure Compound locomotive No 6399 Fury. Designed by Fowler and introduced in 1930, this locomotive was always an experimental design. With a high pressure cylinder of 900psi, it pushed the boundaries of steam boiler design and metallurgical knowledge and tried to utilise a lot of techniques that were in use in the marine engine field. Marine engines were bigger and to cram the necessary machinery within the loading gauge was asking rather too much. Consequently, it didn't perform very well as an express locomotive and was constantly in need of attention. An accident involving a blowout in the cab resulting in death and injury saw a rapid withdrawal and rebuilding into a conventional Royal Scot Class locomotive.
