South Devon Railway Gorgon class
The Gorgon class were six broad gauge locomotives operated on the South Devon Railway, Cornwall Railway and West Cornwall Railway. They were designed for passenger trains on this steep and sharply curved line but were also used on goods trains when required. They were ordered by the South Devon Railway which was contracted to operate the locomotives for both the railways. They were designed by Daniel Gooch a development of his earlier Comet class, and built by the Avonside Engine Company. 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.
