Springburn () is an inner-city district in the north of the Scottish city of Glasgow, made up of generally working-class households. Springburn developed from a rural hamlet at the beginning of the 19th century. Its industrial expansion began with the establishment of a chemical works by Charles Tennant on the newly opened Monkland Canal at nearby St. Rollox in 1799, which later became part of the United Alkali Company. Later in the 19th century, the construction of railway lines through the area led to the establishment of railway works and the village became a parish in its own right. The Garnkirk and Glasgow Railway first opened in 1831 to supply the St. Rollox Chemical Works and the Edinburgh & Glasgow Railway was opened in 1842. Later, the City Union Line was extended to Springburn in 1871, and the Hamiltonhill Branch Line opened in 1894. Initially located outside the Glasgow boundary, the core area was eventually absorbed by the city in 1872 and other parts in 1891. In the early 21st century, it forms part of the Springburn/Robroyston ward under Glasgow City Council. Industrial development The area's economic development has a strong historical link to heavy industry, particularly railways, with the manufacturing of locomotives. In the past, Springburn's locomotive industry had a 25% global market share. There were four main railway manufacturing sites that located in Springburn; the North British Railway's (NBR) Cowlairs Works in 1841, the Caledonian Railway's St Rollox Works in 1856, Neilson & Company's Hyde Park Works in 1861 and Sharp, Stewart & Company's Atlas Works in 1888. The latter two eventually amalgamated to become part of the North British Locomotive Company (NBL) in 1903. Also located in Springburn is the Eastfield Running Shed, originally built by the NBR near the Cowlairs Works in 1904. St Rollox became the largest works, and is the only one still in existence, after the collapse of the NBL in 1962 and the closure of Cowlairs in 1968. In 2007 Railcare Limited, who also owned the Wolverton Works in Milton Keynes, took over operations at St Rollox, from Alstom, who had originally acquired the works from British Rail Engineering Limited in the wake of the railway privatisation. It closed in 2019. The former Eastfield Running Sheds are now operated as a maintenance depot by ScotRail and part of the former Cowlairs carriage sidings is now operated as a signalling and maintenance depot
