The first 19 locomotives ordered by Isambard Kingdom Brunel for the Great Western Railway included three 2-2-2 Sharp, Roberts locomotives. They were built by Sharp, Roberts and Company and the most successful of the early designs, two lasting until the 1870s.

The original 14-by-15-inch (356 mm × 381 mm) cylinders were replaced from 1844 by larger 14-by-18-inch (356 mm × 457 mm) or 15-by-18-inch (381 mm × 457 mm) ones.
