The Île de France was an international express train on the PBA route (Paris–Brussels–Amsterdam). The train was named after the French region surrounding Paris.[1]
Trans Europ Express
The Île de France was the French share of the initial Trans Europ Express (TEE) services on the PBA route. On 2 June 1957 the TEE services on the PBA route started with three trains. One of them, the TEE L'Oiseau Bleu, only served the Paris–Brussels section; the other, the TEE Étoile du Nord, linked Amsterdam with Paris. Both were existing services upgraded to TEE and were operated by Dutch and Belgian railways. The Île de France was introduced as the "mirror" of the Étoile du Nord, that started in the morning in Amsterdam and returned to Amsterdam just before dinner. In order to have a morning service from Paris to Amsterdam, returning from Amsterdam in the evening the Île de France was added at the start of the TEE network.[2]
