The Liverpool and Manchester Railway (L&M) opened on 15 September 1830. Work on the L&M had begun in the 1820s, to connect the major industrial city of Manchester with the nearest deep water port at the Port of Liverpool, 35 miles (56 km) away. Although horse-drawn railways already existed elsewhere, and a few industrial sites already used primitive steam locomotives for bulk haulage, the L&M was the first locomotive-hauled railway to connect two major cities, and the first to provide a scheduled passenger service.
