Some tank engines were sold to London Transport, where steam traction remained in use until 1971. Steam on industrial lines remained until the 1980s. With regular maintenance, British steam locomotives typically lasted for approximately 30 years of intensive use, before major components would need to be replaced or overhauled.
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]
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.

The trial proved successful and a steam rail motor was designed by the Chief Mechanical Engineer George Jackson Churchward. Two units were manufactured, and they entered service on the same route on 12 October 1903. A further 44 were built during 1904 and 1905, and by the time production finished in 1908 the fleet numbered 99 carriage units.
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.
When the GWR was nationalised as part of British Railways in 1948, its steam locomotives retained their numbers unchanged and new steam engines built to GWR designs continued to be allocated numbers in the same way as the GWR had done. However, its diesel locomotives were completely renumbered.

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.
