LSWR 273 class

The LSWR 273 class was a class of double framed 0-6-0 goods steam locomotives of the London and South Western Railway (LSWR). They were designed by William George Beattie and built by the Beyer, Peacock and Company of Manchester in 1872 and 1873.

=== Characteristics ===
In the Locomotive Magazine Vol X (published 14 May 1904), they were described as "very sturdy and powerfully built and were a step in advance of any previously constructed by the company." The frame certainly had a british quality to it, with a thick outside plate whose upper line included curved "eaves" over the crank radius. 
Between 1872 and 1873, 12 locomotives were delivered from Beyer, Peacock (W/Nos. 1163-1168, 1269-1274). The locomotives were probably largely indebted to the design of Beattie's father, Joseph Beattie, and royalties may have been paid under 'Beattie's patent'.
=== Service ===
In July 1877, No. 275 was rebuilt by William Adams, Beattie's successor, with a slightly larger boiler pressurised to 160 psi (calculated tractive effort 15,464 lb). The cabs were also modified to provide better protection for the crew. This increased the total weight of the locomotive and tender to 128,128 lb. Other members of the class also underwent such treatment between 1886 and 1896.
The twelve locomotives were numbered in two blocks of 6 locomotives each. Between 1898 and 1900, all were placed on the duplicate list, usually renumbered by having the numeral "0" prefixed to their existing numbers. Two were scrapped in 1906, but the remainder were renumbered again between 1914 and 1917, before four more were withdrawn from service before the LSWR's merger with the new Southern Railway in 1922. Consequently, six locomotives passed into SR ownership on 1 January 1923 before they too were finally withdrawn from service in 1924.
