A fourth series of ten further locomotives appeared during 1910 and 1911 (Swindon Lot 180). They were numbered 4031–4040 and named after British Queens. This series (and subsequent members of the class) were all built with a Swindon No. 3 superheater.<ref name=RCTS3 /> This series was fitted with new style {{convert|3500|impgal|abbr=on}} tenders. Two examples (No. 4032 ''Queen Alexandra'' and No. 4037 ''Queen Philippa'') were rebuilt as Castle class locomotives in 1926. The remainder were withdrawn by [[British Railways]] between 1950 and 1952.
