Passengers at Charles de Gaulle (CDG), one of the world's busiest airports, enjoy easy access to commuter and high-speed trains. Commuter trains depart every 10-15 minutes and reach central Paris in 28 minutes. The same rail line continues to Orly, Paris' second airport, allowing for simple transfers.

CDG also enjoys full access to Europe's high-speed rail network. High-speed trains now serve many air routes, such as Air France's Paris-Brussels service. On this type of service, connecting passengers purchase one ticket and their baggage is checked through to their final destination.

CDG is a great example of how integrating the air and rail networks allows for a more efficient, convenient transportation system. Passengers can enjoy long-haul, international connections that begin at a convenient location in a city center. Simultaneously, airlines can attract large levels of passengers, without having to run wasteful, costly short-haul flights.
