The ten Buffalo class locomotives were broad gauge locomotives operated on the South Devon Railway, Cornwall Railway and West Cornwall Railway. They were designed for goods trains but were also used on passenger trains when required. These locomotives were built by the Avonside Engine Company and designed for easy conversion to standard gauge after the broad gauge was converted on 21 May 1892. The locomotives of the three railways were operated as a combined fleet by the South Devon Railway but each was accounted to the railway that ordered it. On 1 February 1876 the South Devon Railway was amalgamated with the Great Western Railway, the locomotives were given numbers by their new owners but continued to carry their names too.
