Joseph Hamilton Beattie

Joseph Hamilton Beattie (1808–1871) was an Irish-born British locomotive engineer who served as Locomotive Superintendent of the London and South Western Railway at Nine Elms Works from 1850 until his death in 1871. He had previously been the LSWR's Carriage Superintendent for thirteen years.

Born at Coleraine, County Londonderry on 6 May 1808, Beattie was educated at Trinity College Dublin and joined the LSWR in 1837 under Joseph Locke. He is associated with experiments to improve fuel economy by burning a mixture of coke and coal, the development of the Beattie firebox, and with the introduction of well-tank designs for the West London suburban services. The 'Beattie Well Tanks' built in 1874–1875 to his son William's designs continued his pattern and three lasted in service on the Wenford Bridge mineral branch in Cornwall until 1962.

Beattie died in office at London on 18 October 1871 and was succeeded by his son.
