Lithograph drawn by John Cooke Bourne (1814-1896) as the frontispiece of his book 'The History and Description of the Great Western Railway', published in 1846. The Gooch 'Firefly' clas steam locomotive, Acheron, is shown emerging from the archway of a tunnel between Bath and Bristol, which bears the title of Bourne's book as if carved into the rock. 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.
