Andrew Barclay

Andrew Barclay (1814–1900) was a Scottish locomotive engineer and founder of Andrew Barclay Sons & Co. of Kilmarnock, Scotland's longest-established and ultimately last commercial locomotive builder. The firm specialised in small industrial steam locomotives and side-tank engines, particularly the 0-4-0ST and 0-6-0ST types that became the standard British colliery and works shunter from the 1880s.

Born at Tundergarth, Dumfriesshire on 5 August 1814, Barclay set up as a millwright and founded the Caledonia Engine Works at Kilmarnock in 1840. He concentrated on locomotive building from 1859. The works supplied engines to British and overseas customers and continued in business, as Hunslet-Barclay from 1989, into the present century. Barclay retired from active management in 1892. He died at Kilmarnock on 21 August 1900.
