The Midland Railway (MR) was a railway company in the United Kingdom from 1844. The Midland was one of the largest railway companies in Britain in the early 20th century, and the largest employer in Derby, where it had its headquarters. It amalgamated with several other railways to create the London, Midland and Scottish Railway at grouping in 1923.
The Midland had a large network of lines emanating from Derby, stretching to London St Pancras, Manchester, Carlisle, Birmingham, and the South West. It expanded as much through acquisitions as by building its own lines. It also operated ships from Heysham in Lancashire to Douglas and Belfast. A large amount of the Midland's infrastructure remains in use and visible, such as the Midland Main Line and the Settle–Carlisle line, and some of its railway hotels still bear the name Midland Hotel.
The Midland Railway originated from 1832 in Leicestershire / Nottinghamshire, with the purpose of serving the needs of local coal owners.
The company was formed on 10 May 1844 by the merger of the Midland Counties Railway, the North Midland Railway, and the Birmingham and Derby Junction Railway, the Birmingham and Gloucester Railway joined two years later. These met at the Tri-Junct station at Derby, where the MR established its locomotive and later its carriage and wagon works.
Leading it were George Hudson from the North Midland, and John Ellis from the Midland Counties. James Allport from the Birmingham and Derby Junction Railway found a place elsewhere in Hudson's empire with the York, Newcastle and Berwick Railway, though he later returned.
The MR was in a commanding position having its Derby headquarters at the junctions of the two main routes from London to Scotland, by its connections to the London and Birmingham Railway in the south, and from York via the York and North Midland Railway in the north.
Almost immediately it took over the Sheffield and Rotherham Railway and the Erewash Valley Line in 1845, the latter giving access to the Nottinghamshire and Derbyshire coalfields.
