Engraving by I Shaw Jnr showing a train pasing over the Sankey Viaduct on the Liverpool & Manchester Railway. The viaduct was erected for the railway in 1830 under the direction of George Stephenson (1781-1848). Designed by William Allcard, it was built of brick with stone facings, costing the company £45,000. Each of the nine arches spanned 50 feet, rising from slabs of local sandstone.
