Train service in France is efficient, punctual, and comfortable. It is one of the most popular ways to get around, allowing travelers to view the countryside in a swift, but leisurely manner. France's extensive railway network connects large cities and towns throughout the country. Smaller towns without train stations are generally linked by bus service to the nearest station. The French National Railroads' (Société Nationale des Chemins de Fer or SNCF, www.sncf.fr) network of inter-city rail links also provides frequent express and high-speed train service known as the TGV or Train à Grande Vitesse. Operating at a commercial speeds of 186mph, the high-speed network also includes European routes, featuring the Eurostar which connects Paris to London in just 2h35 and the Thalys going to Brussels and Amsterdam in 1h30 and 4 hours respectively. For added convenience, the Paris Charles-de-Gaulle and Lyon Saint-Exupery Airports have high-speed train stations.
