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The LNWR reused numbers and names from withdrawn locomotives with the result that the numbering system was completely haphazard.

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.

Withdrawals had started in 1907, and the last was withdrawn in 1936. None were preserved.

Accidents and incidents

  • On 15 August 1895, locomotive No. 2159 Shark was one of two locomotives hauling an express passenger train that derailed at Preston, Lancashire due to excessive speed on a curve. One person was killed.[1]
