Side elevation drawing taken from the book 'Locomotives of the GWR 1857' showing a Great Western Railway (GWR) locomotive of the 'Iron Duke' class. Beneath the image, the names of 30 locomotives of this classbuilt for the GWR are listed, with a description of the engines' main features. The GWR was built from 1835 to provide a route from Bristol to London, using broad gauge track developed by Isambard Kingdom Brunel (1806-1859). The line opened fully in 1841. The railway was converted to standard gauge track in 1892. Until 1864 many of the GWR's locomotives were designed by Sir Daniel Gooch (1816-1889), who built a total of 340 engines for the railway at Swindon. The Iron Duke Class locomotives were capable of speeds approaching 80 mph.
