Opening of the Rouen to Le Havre line

On June 5, 1845, the Paris-Rouen Railway Company inaugurated the extension from Rouen to Le Havre, marking a major step in France's early rail network. This 85-kilometer line overcame challenging terrain along the Seine River valley using innovative engineering by British contractors Joseph Locke and Thomas Brassey. Key locomotives included early 2-2-2 express types built by Sharp Brothers. The opening allowed faster travel between Paris and the port of Le Havre, reducing journey times from days by coach to hours by train and spurring trade in cotton and passengers. It connected to broader European networks and influenced French railway standardization. Lasting impact includes the line's role in Normandy's industrial growth and its evolution into today's modern SNCF routes. Model railroaders often recreate its scenic viaducts and early steam operations.
