In the infobox (right) 'ns' denotes non-superheated and 'su' denotes superheated. Some locomotives later had their superheaters removed but the piston valves were retained.
Thirty-four locomotives survived into British Railways ownership in 1948 and their BR numbers were 65600-65644 (with gaps).
Withdrawals started under LNER ownership in 1933. British Railways quickly withdrew the remaining locomotives and all had gone by the end of 1951. None is preserved.
