Trams in France go back to 1837 when a 15 km steam tram line connected Montrond-les-Bains and Montbrison in the Loire. With the development of electric trams at the end of the 19th century, networks proliferated in French cities over a period of 15 years. Although nearly all of the country's tram systems were replaced by bus services in the 1930s or shortly after the Second World War, France is now in the forefront of the revival of tramways and light rail systems around the globe. Only tram lines in Lille and Saint-Étienne have operated continuously since the 19th century; the Marseille tramway system ran continuously until 2004 and only closed then for 3 years (until 2007) for extensive refurbishment into a modern tram network. Since the opening of the Nantes tramway in 1985, more than twenty towns and cities across France have built new tram lines. As of 2013, there are 25 operational tram networks in France, with 3 under construction and 4 more planned. France is also home to Alstom, a leading tram manufacturer.
One of the key inventions in the world history of trams was that of the girder rail developed in 1852 by Frenchman Alphonse Loubat. It brought the tram track down to road level, avoiding accidents to pedestrians and other vehicles caused by the standard protruding rail used until then. Inspired by John Stephenson of New York City, it was in Paris that Loubat built the first line of this type, for horse trams, which was inaugurated on 21 November 1853 in connection with the 1855 World Fair. On a trial basis, it ran along the banks of the Seine from the Place de la Concorde to the Pont de Sèvres in the village of Boulogne.
