[1] The Île de France was the French share of the initial Trans Europ Express (TEE) services on the PBA route.

Meanwhile, the French started the development of locomotive-hauled TEE coaches and multi-system electric locomotives.

The Swiss were the first to introduce quadruple-voltage TEE trainsets in 1961; the French presented their class CC 40100 in 1964.

[3] On 2 August 1964 all TEE services on the PBA-route received Inox-PBA stock operated by the SNCF and NMBS.

In 1987 the Île de France was, like the other PBA TEE services, integrated into the new EuroCity network.
