Easterbrook, Walter John
Born 23 January 1842 at Ippleton in Devon. His father was a yeoman farmer. He joined the GWR in the late 1850s and in the period 1863/4 had become a fitter with Saxby & Farmer. On 18 June 1865 he maried Mary Ann Stockbridge at Willesden Parish Church. Was successful in patenting improvements in interlocking although this led to his dismissal and a series of further patents both from him and from his former employer Saxby. In this effort Easterbrook received financial backing from Georhe Henry Hannaford. In the end there was a Court case which took th form of the Great Western Railway versus Easterbrook held between 14 May and 15 July 1865. Saxby used Sir Frederick Bramwell and John Imray to appear on their behalf and Easterbrook lost and had to leave the field of signalling. He subsequently lived in Bristol and died on 19 January 1914.

In 1882 appointed assistant signal superintendent LYR. Between 1885 and 1889 in service of LSWR under Jacomb-Hood, the chief engineer, when he designed and carried out extensive alterations to the signalling at Victoria station (KPJ seems improbable location, but brother of Jacomb-Hood was associated with LBSCR) and elsewhere.

In 1901 formed the British Pneumatic Railway Signal Co and started the first works for the manufacture of pneumatic tools on a considerable scale in Britain. He installed the first automatic signals on passenger lines. Extensive contracts were implemented under his direction on the GER, LSWR, Central Argentine and other railways. At Victoria station, London, SECR, he installed the first 3-position all-electric interlocking system. He was a prolific inventor and member of many technical societies. He was managing director of the Superheater Corporation Ltd and of British Power Signalling Co Ltd. Marshall

Saxby, John
Marshall notes John Saxby was born in Brighton on 17 August 1821 and was the inventor of signal interlocking. At 13 began as a carpenter's apprentice. Later employed on LBSCR as a carpenter. Saxby became interested in problems of railway safety following several accidents, particularly one at Bricklayers' Arms, resulting from irregular working. He patented his system of interlocking of points and signals in 1856 and it was first applied in that year at Bricklayers' Arms. The first interlocking frame of the type which became universal was installed on the LBSCR near Haywards Heath. Saxby was employed by the LBSCR for 22 yrs. He introduced important improvements in the original 1856 patent in 1860 and 1867. The success of the system was such that in 1861 he started his own business at Haywards Heath to manufacure signalling apparatus. In 1862 he formed with J.S. Farmer the firm of Saxby & Farmer, beside the LNWR at Kilburn. They were sole signalling contractors to the LNWR and LBSCR. Easterbrook had been employed by Saxby & Farmer and attempted to exploit his own improved form of interlocking. In 1871 they introduced the 'rocker & grid' interlocking frame. In 1878 works were established at Creil near Paris, managed by Saxby's son James. His partnership with Farmer ended in 1888, Farmer remaining at Kilburn until his death. In 1889 the French works became part of John Saxby Ltd and in 1893, with the Kilburn works, Saxby & Farmer Ltd. In 1902 Evans O'Donnell & Co of Chippenham was leased to Saxby & Farmer and in 1903 manufacture was transferred there. He died in Hassocks, Sussex on 22 April 1913. He had become a Member of the Institution of Mechanical Engineers in 1880.

Marshall notes that Sykes was born in London in April 1840 and died in Whitstable on 2 October 1917. He was the inventor of the lock & block signalling system. Floyd (Rly Mag, 1, 141) notes that he had "a dry fund of humour". In 1854 he was working for the Electric & International Telegraph Co. In 1861 he moved to Shepherds, an electric clock & chronograph maker. In 1863 he joined the LCDR under the telegraph superintendent, Mr Ruddall. By 1897 he had 25 patents which included (1865) the hand lamp showing red green or white lights known as "Clarke's Lamp" was invented by Sykes; in 1872 treadles for automatic signalling (but article states was invented by Richardson for the ECR in 1848; in 1875 a device for linking signal cabins; in 1880 the lock & block system; a signal selector (several signals operated by one lever) and electric fouling bar.

Tattersall, Arthur Ewart
Signal Engineer, successively, on the Lancashire and Yorkshire, the Great Southern and Western (Ireland), and then, from 1907, Signalling and Electrical Assistant to the Engineer of the Metropolitan Railway. From 1921, Signal Superintendent, Great Northern Railway, and then, after some intermediate appointments, Signal and Telegraph Engineer, North-Eastern Area, L.N.E.R. Finally, in 1936, he became Signal and Telegraph Engineer, Southern Area, L.N.E.R. Tattersall, more than any other man, could be called the father of modern railway signalling. On the L.N.E.R. he pioneered the use of relay rather than lever interlocking, and the introduction of thumb-switch control panels instead of interlocking frames. He was responsible for the early panel interlockings at Thirsk and Leeds, from the experience of which stemmed the great installations at Hull and York; and in the Southern Area he was responsible for the sequence-switch interlocking at Doncaster and for the complete resignalling of Liverpool Street Station and its approach lines. Warburton (LMS signals No. 17 LMS Journal (19), 47) suggests that Tattersall experimented with colour light signals in 1913. Stanley Hall Railway milestones and millstones.. Nock, O.S.
