Beyer, Peacock and Company was a railway locomotive manufacturer, of Manchester.
1854 Founded by Charles Beyer and Richard Peacock and Mr Robertson . Beyer had been the manager of Sharp Brothers. Peacock had been apprenticed at Fenton, Murray and Jackson and then worked for several railway companies.
1855 First locomotive produced for the Great Western Railway.
Important designs were the Beyer-Garratt articulated locomotives widely used in Africa (and Australia) and the 4-4-0 tank locomotives used on the London Underground from 1864 until electrification in 1905. This design then evolved into a 2-4-0 for Norway and finally the famous Manx Peacock design for the Isle of Man Railway.
The first Garratt locomotive constructed was TGR K Class for the Tasmanian Government Railways on the western Tasmanian North East Dundas Tramway.
1866 Details of a strike at the Gorton Foundry. 
1881 The first of more than 200 tram engines were delivered between 1881 and 1910, presumably under the patent of William Wilkinson (1838-1906). An 1885 example has been preserved at the Crich Tramway Museum (see photo).
1883 The surviving partners formed the partnership into a limited company.
1887 Produced a rack driven locomotive for Venezuela.
1889 Screw-cutting lathe. 
1899 Had their own steel foundry.
1902 The company became public. The company was registered on 3 May, to take over the business of locomotive builders and general engineers. 
1903 "An order has recently been placed by the Japanese Government for twenty four tank locomotives with Messrs. Beyer, Peacock and Co., of Gorton, Manchester, after keen competition. Germany, it appears, has secured an order for eight only from the same Government, which clearly indicates that in spite of the reproach brought against English makers they are still to the front."
1907 Produced their 5,000th locomotive with 1,600 of these for the home market.
1914 Locomotive builders, tool manufacturers, steel founders. Employees 2,300. 
1923 They removed their London office from 15, Dean's-yard, to Abbey House (Rooms 338-340), Westminster, SW.
1926 The directors' report of Beyer, Peacock and Co., Ltd furnished a pleasing example of of revival in the fortunes of a firm which for some time had suffered from the prevailing slump in the engineering industry. The accounts showed a trading profit for the year of £36,423, which was reduced to a net profit of £9547 by the deduction of £7787 for interest on the debenture stock and £16,242 placed to the depreciation reserve. This result compared most favorably with the two preceding years. In 1924, for instance, there was a net loss of £42.508, while in 1923 the net loss was even more, actually £87,000. 
1926 Robert H. Whitelegg was the general manager.
1927 The works occupied 23 acres and employed 3,000 persons.
1927 See Aberconway for information on the company and its history.
1932 Purchased Richard Garrett and Sons ,truck producer.
1949 Formed joint venture company Metropolitan-Vickers-Beyer-Peacock with Metropolitan-Vickers Electrical Co Ltd to design, manufacture and assemble railway locomotives other than steam (this concentrated on electric and diesel electric locomotives). New factory at Stockton-on-Tees.
1958 In order to cover the range of potential rail motive power technologies, formed joint venture with Armstrong Siddeley Development Co Ltd, part of Hawker Siddeley, to manufacture diesel hydraulic locomotives; this was called Beyer Peacock (Hymek) Ltd.
1961 In view of declining rail production, Beyer Peacock reorganised its affairs, making space at Gorton for manufacturing of all types of railway locomotives; Metropolitan-Vickers-Beyer-Peacock was placed into liquidation.
1966 Ceased trading.
