'Expres Tenders', 1857.

Side elevation drawing taken from the book 'Locomotives of the GWR 1857'. Beneath the image of a tender built to this specification for the Great Western Railway (GWR) is a description of the tender's 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 Works.
