followed five years later. In 1958 Beyer, Peacock (Hymek) Ltd was formed. Gorton Foundry Beyer and Peacock started building their Gorton Foundry in 1854 two miles east from the centre of Manchester at Openshaw on a 12-acre site, on the opposite (south) side of the Manchester, Sheffield and Lincolnshire Railway (MS&LR) line from Peacock's previous works. The site was chosen because land was cheaper than in the city, allowing ample room to expand, and there was a good water supply from an MS&LR reservoir. At the Foundry, Beyer designed and manufactured machine tools needed to build the locomotives, and oversaw locomotive design and production. Peacock dealt with the business side, often travelling to continental Europe to secure orders. In July 1855 the first locomotive, built for the Great Western Railway, left Gorton Foundry. Between 1854 and 1868 the company built 844 locomotives, of which 476 were exported. The company sold mainly to the British colonies, Southern Africa and South America. The company had been commissioned by the London and North Western Railway to build a single copy of their Dreadnought Class for the Pennsylvania Railroad, as the former railway's shops were not legally permitted to sell their locomotives. Aside from this locomotive, the company did not enter the North American market. During the First World War Beyer, Peacock manufactured artillery; in August 1915 Gorton Works was put under government control with production switching almost entirely to the war effort, especially heavy field artillery. During the Second World War, the company was again brought under government control but continued to build locomotives throughout the war. Condensing locomotives for underground railways A technological innovation that strengthened the company's reputation was the world's first successful condensing locomotive design for London's first underground railway – the Metropolitan Railway A Class 4-4-0 tank engine. Between 1864 and 1886, 148 were built for various railways; most operated until the lines' electrification in 1905. The locomotives' main designer, Hermann Ludwig Lange (1837–92), was a native of Beyer's home town, Plauen, Saxony (now Germany) who had undertaken an apprenticeship followed by engineering training. Beyer had invited him to England in 1861 and employed him for the first year in the company workshops, then as a draughtsman under his direction. He became chief draughtsman in 1864 or 1865. After Beyer's death in 1876, he became chief engineer and co-manager of the company. Beyer-Garratt articulated locomotives An articulated locomotive design
