The Metropolitan Railway D Class was a group of six 2-4-0T tank engines built for the Metropolitan Railway in 1894-1895 by Sharp, Stewart and Company.
Two locomotives were used on the Verney Junction-Aylesbury section. The other four ran between Aylesbury and Baker Street and were fitted with condensing apparatus, but this was later removed.
From 1920 the class was withdrawn. Some were sold, others scrapped. None were preserved.
