The London and North Western Railway Experiment Class was a series of 30 three-cylinder 2-(2-2)-0 compound locomotives designed by Francis Webb for the London and North Western Railway between 1882 and 1884. They were Webb’s first large-scale experiment with a class of express compound locomotives, and the first engine was named accordingly. They were followed by a class of similar, but larger locomotives, that featured larger boilers and smaller driving wheels – the LNWR Dreadnought Class.
After Webb's retirement, his successor, George Whale, withdrew the Experiment class locomotives soon after he took up office in 1903.
