Opening of the Paris–Le Havre railway

The Paris–Le Havre railway marked a major engineering achievement in mid-19th century France, overcoming challenging terrain including the Seine valley and requiring innovative bridge construction. Key figures included engineer Joseph Locke and contractor Thomas Brassey. The line facilitated rapid transport of goods and passengers, boosting trade between Paris and Normandy ports. It featured early steam locomotives from British manufacturers and helped standardize French rail gauges. This development was crucial during the industrial expansion under Louis-Philippe, linking inland commerce with Atlantic shipping routes. Lasting impact includes its integration into the modern SNCF network and influence on subsequent French rail expansions across Europe.
