Kilmarnock Locomotive Works

Kilmarnock Locomotive Works was the principal locomotive works of the Glasgow & South Western Railway from 1856 until the 1923 Grouping. The works was located in Kilmarnock, Ayrshire, at the heart of the GSWR system, and built locomotives in modest numbers under successive Locomotive Superintendents Patrick Stirling (1853–1866), James Stirling (1866–1878), Hugh Smellie (1878–1890), James Manson (1890–1911) and Peter Drummond (1912–1918).

The first locomotive worked at Kilmarnock dates from 1812 (the Kilmarnock & Troon Railway's locomotive trial), making the town one of the earliest in Scotland with a railway connection. Under the LMS from 1923 and BR from 1948, Kilmarnock Works continued as a heavy-overhaul shop until its closure in 1959. Andrew Barclay's Caledonia Engine Works, the same town's other locomotive builder, continued in business through to the 21st century.
