London and Brighton Railway Opens

On June 20, 1846, the London and Brighton Railway officially opened its 50-mile main line from London Bridge to Brighton, marking a major milestone in British rail expansion. Engineered by John Urie Rastrick, the route featured challenging terrain including the Merstham and Clayton tunnels. The inaugural train, hauled by a Bury 0-4-0 locomotive, carried directors and dignitaries in just over two hours. This line boosted seaside tourism and freight transport of coal and goods, integrating southern England into the national network. It later merged into the London Brighton and South Coast Railway, influencing suburban growth and setting standards for coastal resort development. The engineering feats, such as the impressive Ouse Valley Viaduct completed shortly after, demonstrated Victorian innovation in bridging valleys with 37 arches.
