The A1 Terrier was built at the Brighton Works under the design of William Stroudley in 1872 and between 1874 and 1880 and operated by the LB&SCR primarily on the London lines serving the commuter towns that were rapidly springing up. As the demands placed on the commuter network increased, the A1 Terrier were replaced by heavier more powerful Tank engines and the Terrier was sold to other private operators to work on branch line and shunting operations. Sixteen of the class was modified between 1911 and 1913 and in 1919 with a new boiler and extended smokebox plus some other improvements and were classified A1X. The Class survived well into nationalisation with the final Terrier being decommissioned in 1963. In all 10 terriers survive into preservation.
