DispositionAll scrapped

Twelve locomotives were purchased and placed in service between November 1880 and January 1891. They were placed on the duplicate list and renumbered 0135 to 0146 in 1902. Seven were withdrawn in 1913; the remaining five, 135, 139, 140, 143 and 144 were renumbered in 1914. They became 0370, 0307, 0310, 0312 and 0347 respectively, still on the duplicate list. This renumbering effectively changed their classification to 0307 class. Only two were still in service to pass to the Southern Railway in 1923, but they were withdrawn the following year.
