Thalys services are international high-speed rail links, operated by a joint venture between SNCF, SNCB and Deutsche Bahn. The service's original route ran between Paris and Brussels. It has since been extended considerably to reach main destinations that include Antwerp, Rotterdam, Amsterdam, Bruges and Cologne.
Interestingly, instead of flying between Paris and Brussels, Air France and jet Airways now book their passengers onto Thalys services between the two destinations rather than operate flights. A similar agreement is in place for services between Amsterdam Schiphol Airport and Antwerp and Brussels.
The service's passenger base is split fairly equally between the leisure and business sectors, with the largest proportion of journeys being those between Paris and Brussels.
