The Scinde Railway Company was a railway company established in 1854 in what is now Pakistan. The line initially stretched from Karachi to Kotreem until 1857 when the constitution of the company was modified and contracts were made for the construction of another section of the line from Multan to Amritsar in the Punjab. Contracts were also made for working a Steam Flotilla on the Indus connecting the Scinde and Punjab sections. The company constructed a further line connecting Delhi and Amritsar. The four sections of the railway were at first kept separate and distinct under the names of the Scinde Railway, Indus Flotilla Company, Punjab Railway and Delhi Railway, although conducted through the agency of one company. In 1869 the three railway sections were amalgamated into the Scinde Punjab and Delhi Railway. In 1886 the state acquired and merged the Scinde, Punjab and Delhi Railway‎‎, Punjab Northern Railway, Indus Valley State Railway, eastern section of Sind-Sagar Railway, southern section of Sind Pishin Railway, and Kandhar State Railway. The whole system was brought under direct state management under name North Western State Railway, later renamed as the North Western Railway (NWR).

Slaughter, Edward (1815-1891), Mechanical Engineer, was born in London on the 1st of December 1814. He was educated at the school of Dr Nicholas at Ealing and in Paris and served a pupillage of five years to Mr. John Seaward of the Canal Ironworks, Limehouse. Edward Slaughter joined I K Brunel in 1837 as Assistant Engineer and took part in the construction of the London end of the Great Western Railway in laying the permanent way over a large portion of the line, building stations and general work. Mr. Brunel subsequently gave him a post at the Bristol end of the line. In December 1839 he accepted the offer of Henry Stothert and Co. engineering works in Bristol to join their firm as managing partner, specially manufacturing locomotive engines. The partnership was formed early in 1840 under the name of Stothert, Slaughter and Co., which was changed in 1856 to Slaughter, Gruning and Co. when Henry Gruning joined the company. In 1866 the business was converted to Avonside Engine Company Ltd. and Edward Slaughter became the Managing Director being responsible of the engineering and general management until 1873, when failing health induced him to retire. During this period Edward Slaughter travelled widely abroad working with foreign railways, and supplied nearly one thousand locomotives including some marine and stationary engines and iron steamships. As many of the locomotives were built for foreign railways with steep gradients and sharp curves, he took a prominent part in the introduction of the various articulated or bogie systems. He improved the steamboat service between Bristol and Newport by designing and building two screw-steamers, 'Avon' and 'Severn', which were fitted with engines of the locomotive type working direct on to the screw-shaft. Edward Slaughter was a member of the Institution of Civil Engineers and Institution of Mechanical Engineers from 1853. He died on the 13th of May, 1891.
