The Vauban was an express train that linked Brussels Midi/Zuid in Brussels, Belgium, with France, Switzerland and Italy. Introduced in 1988, it was operated by the National Railway Company of Belgium (NMBS/SNCB), the Chemins de Fer Luxembourgeois (CFL), the SNCF, the Swiss Federal Railways (SBB-CFF-FFS), and the Italian State Railways (FS).
The train is named after Sébastien Le Prestre (1633–1707), Seigneur de Vauban and later Marquis de Vauban (and commonly referred to as Vauban), who was a Marshal of France and the foremost military engineer of his age.
The Vauban was one of two EuroCity train-pairs running daily between Brussels and Basel, Switzerland; the other was the EC Iris.[1]
