The first two locomotives were built at Swindon railway works in 1849 for working trains on the steep and tightly-curve South Devon Railway which at that time was operated by locomotives from the Great Western Railway. The frames only ran from the front of the flangeless forward driving wheels to the rear buffer beam. The bogie swivelled in a ball-and-socket joint, riveted to a gussett under the boiler barrel. The operation of South Devon Railway had been contracted by that company to Messrs Evans and Geach from 1851 – using new 4-4-0STs designed by Daniel Gooch – and so the Bogie Class found use on other parts of the Great Western network.
