Invention and Engineering
Earl of Airlie was an 1833 steam locomotive designed and built by J and C Carmichael for the 4ft 6in gauge Dundee and Newtyle Railway, with a 0-2-4 wheel arrangement and a tender. It was the first steam passenger locomotive in Scotland, the first locomotive in the United Kingdom to have a bogie, and the only 0-2-4 locomotive ever built. A second locomotive, of the same design, Lord Wharncliffe was completed shortly after Earl of Airlie. A third 0-2-4, Trotter, was provided by James Stirling & Co. in 1834, to a similar but sightly smaller design. No other locomotives ever used the 0-2-4 arrangement.
