The [[Great Western Railway]] '''Metropolitan Class''' {{whyte|2-4-0|T}} [[broad gauge]] [[steam locomotive]]s with [[Condensing steam locomotive|condensing apparatus]] were used for working trains on the [[Metropolitan Railway]]. The equipment was later removed, though the class continued to work [[suburban train]]s on GWR lines in [[London]]. The class was introduced into service between June 1862 and October 1864, and withdrawn between June 1871 and December 1877.

Twenty-two locomotives were built to the {{whyte|2-4-0|T}} [[tank locomotive]] arrangement from 1862 to 1864.<ref name="Sheppard, Metropolitan, A43" >{{harvnb|Sheppard|2008|page=28}}, ''Metropolitan'', 2-4-0T</ref>  The locomotives were built by three workshops, each with a different naming system. The first two batches were delivered concurrently by the [[Vulcan Foundry]] (named after insects), and [[Kitson & Co.]] (named after foreign monarchs). These were followed by a batch from the railway's own workshops at [[Swindon railway works|Swindon]], that were named after flowers.

Around 1865, seven of the class were rebuilt as {{whyte|2-4-0}} tender locomotives: ''Hornet'', ''Mogul'', ''Azalia'', ''Lily'', ''Myrtle'', ''Violet'', ''Laurel''.<ref name="Sheppard, Metropolitan, A34" >{{harvnb|Sheppard|2008|page=24}}, ''Metropolitan'', 2-4-0</ref> 

All were withdrawn between 1871 (''Czar'') and 1877 (''Rose'' & ''Shamrock'').<ref name="Sheppard, Metropolitan, A34" />

==Locomotives==
