The London and North Western Railway (LNWR) Waterloo Class was a class of 2-4-0 steam locomotives that was also known as the Whitworth Class.

History

The locomotives were introduced by F. W. Webb in 1889 as replacements for the Samson class, and 90 examples were built up to 1896.

The LNWR reused numbers and names from withdrawn locomotives, with the result that the numbering system was completely haphazard.

Withdrawals had started in 1907, following George Whale's succession of Francis Webb in 1903 and the introduction of Whale's stronger Precursor and Experiment tender engines. Thirty locomotives passed to the London, Midland and Scottish Railway at the 1923 grouping. They were given the power classification 1P, and renumbered 5080–5109. In addition, four other members of the class survived in departmental service.

The last Waterloo was withdrawn in 1936. None were preserved.
