Built by Ashford Works between
February 1909 and June 1910, Wainwright had been impressed by
the LBSCR Terriers, unfortunately in an effort to keep building costs down,
several dimensions were scaled down and these economies resulted in a locomotive
with only 73% of a Terrier's tractive effort. All of the class were re-allocated
to light shunting or shed pilots by 1913.
Four of the class passed into preservation, 50% of
those built, 3 are located on the Bluebell Railway and one No. 1556, on the
K&ESR.
