The first two were ordered from Kitson & Co, Leeds in 1884 to work the steeply graded Eastern Railway from Guildford to Chidlow. A further three were built by Dübs & Co, Glasgow in 1885/86 and a further six by Kitson & Co in 1898. The last batch were built with larger water tanks, with the earlier five having larger tanks retrofitted. In 1903, they were displaced by the K class and relegated to shunting duties.[1][2]
