The steam locomotives of British Railways were used by British Railways over the period 1948–1968. The vast majority of these were inherited from its four constituent companies, the " Big Four ". In addition, BR built 2,537 steam locomotives in the period 1948–1960, 1,538 to pre-nationalisation designs and 999 to its own standard designs.
Newcomen's atmospheric steam engine. The first practical mechanical steam engine was introduced by Thomas Newcomen in 1712. Newcomen apparently conceived his machine independently of Savery, but as the latter had taken out a wide-ranging patent, Newcomen and his associates were obliged to come to an arrangement with him, marketing the engine until 1733 under a joint patent.

Developed for Charles Porter by Charles Richard, the steam engine indicator traces on paper the pressure in the cylinder throughout the cycle, which can be used to spot various problems and to optimize efficiency. [14] [19] Earlier versions of the steam engine indicator were in use by 1851, though relatively unknown. [20]

Steam engines of this kind propelled the Industrial Revolution in Great Britain and the world. The Watt steam engine design was an invention of James Watt that became synonymous with steam engines during the Industrial Revolution, and it was many years before significantly new designs began to replace the basic Watt design.
The Watt steam engine was conceived in 1765. James Watt transformed the steam engine from a reciprocating motion that was used for pumping to a rotating motion suited to industrial applications. Watt and others significantly improved the efficiency of the steam engine. 1701. An improved seed drill is designed by Jethro Tull. [12]
The GWR 5700 Class (or 57xx class) is a class of 0-6-0 PT steam locomotive built by the Great Western Railway (GWR) and British Railways (BR) between 1929 and 1950. With 863 built, they were the most prolific class of the GWR, and one of the most numerous classes of British steam locomotive.
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
