GWR 927 Class
Numbered in the series 927-946, the 927s were essentially a variant of Armstrong's own Standard Goods (388) Class, with driving wheels of 4'6" rather than 5'0" diameter. They were specifically designed for the heavy trains between Pontypool Road and the Mersey that conveyed Welsh steam coal to the transatlantic shipping lines. (Previous GWR classes used on this work were Daniel Gooch's 79 Class 0-6-0s, and Gooch's later 0-6-0s built by Beyer, Peacock, the 322 Class).
Most of the 927s were allocated to Birkenhead shed, and they were withdrawn between 1905 and 1928.
