The class were powerful locomotives for their time and the design was "an archetype for heavy goods engines in Scotland as well as Southern England," but in other respects were Stroudley's least successful design, suffering from poorsteaming. Within a decade of their introduction the class was being replaced by his C1 class0-6-0 design of 1882–87 on the heaviest trains. Nevertheless, they proved to be reliable locomotives and survived for nearly thirty years on secondary freight duties. Members of the class were withdrawn between 1901 and 1904.
