'''John Gray''' was an early English [[steam locomotive]] engineer who introduced several innovations in locomotive design during the 1830s and 1840s. John Gray's origins were thought to be unknown but he appears to have originated from Newcastle.<ref name=":0">{{cite book|last=Marshall|first=John|title=A Biographical Dictionary of Railway Engineers|publisher=David and Charles|location=Newton Abbot, England|year=1978|isbn=0-7153-7489-3}}</ref> John Gray was born 29 August 1810 in Newcastle upon Tyne, Northumberland, England.<ref>{{Cite web|url=http://www.ancestry.co.uk|title=1851 England Census|last=|first=|date=|website=|archive-url=|archive-date=|access-date=}}</ref>

==Career==
===Innovations===
In 1838 he was working for the [[Liverpool and Manchester Railway]] where he was the first engineer to use the [[balanced slide valve]] on locomotives, and later applied a form of [[Expansion valve (steam engine)|expansion gear]].<ref name=":0" /> In 1840 he was appointed locomotive superintendent of the [[Hull and Selby Railway]] where he became the first locomotive engineer to use long-travel valve motion.

===Locomotive superintendent===
In 1845 he was appointed locomotive superintendent of the [[Brighton, Croydon and Dover Joint Committee|Croydon Dover and Brighton Joint Committee]], which then operated the pooled locomotive fleets of the [[London and Croydon Railway]], the [[South Eastern Railway (UK)|South Eastern Railway]] and the [[London and Brighton Railway]]. On the dissolution of this committee and the formation of the [[London Brighton and South Coast Railway]] in 1846 Gray was appointed [[Locomotive Superintendent]] at [[Brighton railway works|Brighton works]]. However in 1847 he was dismissed from this post as a result of problems over the late delivery of locomotives from [[Timothy Hackworth]].<ref>{{cite book|last=Bradley|first=D.L.|title=Locomotives of the London Brighton and South Coast Railway.
