1840 Designed engines for the Hull and Selby
1845 'Mr. John Gray, C. E., resident engineer and superintendent of the works of the Hull and Selby Railway, has resigned his situation, having accepted an engagement at a higher salary the London and Brighton Railway. Mr. Gray has been the service of the Hull and Selby Company ever since the opening of the line, and during that period has been the inventor of several valuable improvements in connection with the steam engine and machinery, among which we may mention the expansive motion, by which increase of power as well as a considerable saving in the fuel of locomotive engines has resulted.'[1]
From 1846 onwards there was a great development of John Gray's mixed framed engine, with inside bearings only for the driving axle and outside bearings for the leading and trailing axles.
Gray, engineer of the London and Brighton Railway, was responsible for some very successful engines; he designed twelve express engines for the company that were built in 1846-8 by Timothy Hackworth at Shildon.
1847 David Joy, chief draughtsman of E. B. Wilson and Co, spent three weeks studying John Gray's locomotive design at Brighton, and then produced a similar design, the Jenny Lind.
1857 Wrote to The Engineer from Freeman's Journal Office, Dublin.
