The railway network of France, which stretches 31,840 kilometres (19,784 mi) is the most extensive in Western Europe. It is operated by the SNCF, and high-speed trains include the Thalys, the Eurostar and TGV, which travels at 320 km/h (200 mph) in commercial use. The Eurostar, along with the Eurotunnel Shuttle, connects with the United Kingdom through the Channel Tunnel. Rail connections exist to all other neighbouring countries in Europe, except Andorra. Intra-urban connections are also well developed with both underground services and tramway services complementing bus services.
