The LSWR 273 class was a class of double framed 0-6-0 steam locomotives designed by William George Beattie for the London and South Western Railway (LSWR). Twelve locomotives were built between 1872 and 1873. [1]

Numbering

The twelve locomotives were numbered in two blocks of 6 locomotives each. Between 1898 and 1900, all were placed on the duplicate list, usually by prefix the number with a "0". Two were scrapped in 1906, but the remainder were renumbered again in 1914–1917 before four more were retired prior to the 1923 grouping, leaving six to pass into Southern Railway ownership on 1 January 1923, before they too were withdrawn and scrapped.

The Southern Railway took a key role in expanding the 660 V DC third rail electrified network begun by the London & South Western Railway. As a result of this, and its smaller operating area, its steam locomotive stock was the smallest of the 'Big Four' companies.

The LSWR N15 class was a British 2–cylinder 4-6-0 express passenger steam locomotive designed by Robert Urie. The class has a complex build history spanning three sub-classes and ten years of construction from 1918 to 1927. The first batch of the class was constructed for the London and South Western Railway (LSWR), where they hauled heavy express passenger trains to the south coast ports and further west to Exeter. After the Lord Nelsons, they were the second biggest 4-6-0 passenger locomotives on the Southern Railway. They could reach speeds of up to 90 mph (145 km/h).

The London and South Western Railway (LSWR) 0298 Class or Beattie Well Tank is a class of British steam locomotive. They are 2-4-0WTs, originally built between 1863 and 1875 for use on passenger services in the suburbs of London, but later used on rural services in South West England. Out of a total production of 85, two locomotives have been preserved, both in operational condition.

The LSWR M7 class is a class of 0-4-4T passenger tank locomotive built between 1897 and 1911. The class was designed by Dugald Drummond for use on the intensive London network of the London and South Western Railway (LSWR), and performed well in such tasks. Because of their utility, 105 were built and the class went through several modifications over five production batches. For this reason there were detail variations such as frame length. Many of the class were fitted with push-pull operation gear that enabled efficient use on branch line duties without the need to change to the other end of its train at the end of a journey.

Three C14 remained with the LSWR and were rebuilt as 0-4-0Ts. They lasted until the late 1950s.
