The Consett Iron Company Ltd was an industrial business based in the Consett area of County Durham in the United Kingdom. The company owned coal mines and limestone quarries, and manufactured iron and steel. It was registered on 4 April 1864 as successor to the Derwent & Consett Iron Company Ltd. This in turn was the successor to the Derwent Iron Company, founded in 1840.

The Stockton and Darlington Railway (S&DR) was a railway company that operated in north-east England from 1825 to 1863. The world's first public railway to use steam locomotives, its first line connected collieries near Shildon with Darlington and Stockton in County Durham, and was officially opened on 27 September 1825. The movement of coal to ships rapidly became a lucrative business, and the line was soon extended to a new port at Middlesbrough. While coal waggons were hauled by steam locomotives from the start, passengers were carried in coaches drawn by horses until carriages hauled by steam locomotives were introduced in 1833.
