They were ordered by Evans and Geach who were contracted to operate the railway's locomotives. They were designed by Daniel Gooch and based on his Banking Class locomotives built for the Great Western Railway who had previously operated the South Devon Railway, and built by the Vulcan Foundry.

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.

Three similar locomotives were built for the Vale of Neath Railway in 1854. Some of these could be found working on the South Devon lines after the 1876 amalgamation.
