The Great Western Railway Metropolitan Class 2-4-0T broad gauge steam locomotives with condensing apparatus were used for working trains on the Metropolitan Railway. The equipment was later removed, though the class continued to work suburban trains 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 The class was introduced into service between June 1862 and October 1864, and withdrawn between June 1871 and December 1877. Around 1865, seven of the class were rebuilt as 2-4-0 tender locomotives: Hornet, Mogul, Azalia, Lily, Myrtle, Violet, Laurel. All were withdrawn between 1871 (Czar) and 1877 (Rose & Shamrock).
