The Gorgon class were six 4-4-0 saddle tank 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.
South Devon Railway
- Gorgon (1866 – 1892) GWR no. 2122
- On a foggy Christmas Day in 1883, Gorgon was put on the front of a train at Newton Abbot railway station to assist it over the heavy gradients to the west. After leaving the station the driver realised that he did not have the train behind him. The driver slowed down, only for the remainder of the train to emerge from the fog and collide with his locomotive. Gorgon was named after a Greek mythological monster, the Gorgon.
- Sedley (1866 – 1885) GWR no. 2124
- Sedley was the first broad gauge locomotive to take a passenger train through to Penzance when the West Cornwall Railway was converted to mixed gauge. The derivation of this name is uncertain.
- Sol (1866 – 1892) GWR no. 2125
- The word Sol is the Sun in Latin.
