The Great Western Railway (GWR) 2221 Class or County Tank was a class of 4-4-2T steam locomotive, effectively a tank engine version of the 3800 "County" Class 4-4-0 tender locomotives. The two classes had different boilers, standard no 4 for the tender locomotive, and the smaller (by about 350 sq ft or 33 m2) standard no 2 for the tank. 2230 was fitted with the larger boiler when new, but this was unsuccessful and was quickly altered.[2]
