Thunderer was the first of a pair of steam locomotives (the other being Hurricane) built for the Great Western Railway (GWR), England, by R. & W. Hawthorn & Co. whose design was very different from other locomotives. 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.

The locomotive was delivered to the GWR on 6 March 1838 and ceased work in December 1839[1] after running only 9,882 miles (15,904 km), but its boiler section was kept as a stationary boiler.
