The Sligo, Leitrim and Northern Counties Railway Leitrim Class was a class of five 0-6-4T locomotives built by Beyer, Peacock and Company between 1882 and 1889 for the SLNCR.
In 1879 Beyer, Peacock and Company supplied the South Australian Railways K class, which was built to the Irish gauge and designed to run on lightweight track. As a result, and after the disappointment of the Pioneer class, the SL&NCR ordered an enlarged version of this design which became the SLNCR Leitrim class.[3][4]
Beyer, Peacock delivered the first two of this class Fermanagh and Leitrim, in 1882. They proved to be reliable and the SL&NCR obtained further examples from Beyer, Peacock: Lurganboy in 1895; Lissadell and Hazelwood in 1899.[2] The SL&NCR started withdrawing the class from service in 1947 and one of the class survived until the closure of the line in 1957.[4] "Lissadell" was sold in working order to Hammond Lane Foundry in 1954 and survived until broken up at Manorhamilton in 1957.[5]
