Thalys (French: [talis]) was a brand name used for high-speed train services between Paris Gare du Nord and both Amsterdam Centraal and German cities in the Rhein-Ruhr, including Aachen, Cologne, Düsseldorf, Duisburg, Essen and Dortmund, both via Brussels-South.
Thalys was created out of a political ambition formalised in October 1987 to establish a network of international high-speed railway services between the cities of Paris, Brussels, Cologne and Amsterdam. The Thalys name was created in January 1995. The company procured a fleet of Alstom-built TGV trains to operate its services as they were viewed as the only existing rolling stock suitable to the task.
