Thunderer was one of a pair of very different locomotives built for the Great Western Railway, England, by R and W Hawthorn and Company. In order to meet Isambard Kingdom Brunel's strict specifications, an 0-4-0 frame carried the 'engine', while the boiler was on a separate six-wheeled frame. The driving wheels were geared 10:27 in order to reduce the cylinder stroke speed while allowing high track speed, in line with the specifications.

It was withdrawn in 1839 after running only 9,882 miles, but its boiler section was kept as a stationary boiler.
