Neilson and Company was a locomotive manufacturer in Glasgow, Scotland. The company was started in 1836 at McAlpine Street by Walter Neilson and James Mitchell to manufacture marine and stationary engines. In 1837 the firm moved to Hyde Park Street and was known as Kerr, Mitchell and Neilson and, in 1840, Kerr, Neilson and Company, becoming Neilson and Mitchell in 1843. Locomotive building began in 1843 for the local railways. In 1855 production of marine and stationary engines discontinued and the company changed its name again to Neilson and Company. Among those who later became notable in the field were Henry Dübs and Patrick Stirling. By 1861, business had increased to such an extent, that a new works was built at Springburn, also named "Hyde Park Works." In 1864, Henry Dübs set up in business on his own at Queens Park Works, as Dübs and Company, taking a number of key staff with him. James Reid, who had previously worked for Neilson, however, returned and became a partner.
Stationary Engines
When the Edinburgh and Glasgow railway was opened in 1842, it used a pair of Neilson & Mitchell beam engines to work the rope incline from Glasgow to Cowlairs station. The engines were covered by an article illustrated with drawings in The Practical Mechanic and Engineer's Magazine in Jan 1844. They were beam engines mounted on an entablature supported on fluted columns. The engines had 28 inch cylinders, and 6 foot stroke. They were supplied with steam at 50psi by 8 boilers, each 30 foot long and 5 foot diameter.
Locomotives
By 1855, the company was building four-coupled tank engines, along with 2-4-0 and 0-4-2 tender locos. Some of these were for Cowlairs and St. Rollox, but many more went to India. Through the 1870s considerable numbers of 0-4-4 tank engines were built for the London, Chatham and Dover Railway, the Midland and the Great Eastern. Many other types were built for railways at home and abroad, including fifty 0-4-2s for India. The company's first eight-coupled locos were built in 1872, also for India. In 1879 the first 2-6-0s to run on British rails were built for William Adams of the Great Eastern. One of these was named "Mogul" and this became the name applied to all locomotives of this wheel arrangement. More overseas orders followed, with engines for South Africa and South America.
In 1884, Neilson left to form a new company, the Clyde Locomotive Company; although Reid became the sole owner of Neilson & Co., it was not until 1898 that the company changed its name to Neilson, Reid and Company. However, by this time, intense competition from United States meant that small companies were unable to survive. There was a need for amalgamation, and in 1903 Neilson Reid combined with Dübs and Company and Sharp Stewart and Company to form the North British Locomotive Company, the largest locomotive company in the world outside the United States.
Neilson and Company supplied the first and last members of the 88-strong New Zealand RailwaysF class. Six builders supplied F class engines between the arrivals of F13 and F216.
A character in The Railway Series by the Rev. W. Awdry is based on a Neilson prototype. Neil is a 'box tank' locomotive, who worked on the Sodor & Mainland Railway between 1856 and 1901.
