In May 1958, a route to Nice via Lyon was introduced. A temporary service to Brussels via Antwerp operated that year to serve the Brussels International Exhibition. In December, it was announced that an experimental scheme to allow British and Irish subjects to make day-trips abroad without needing a passport was to be introduced on a limited number of routes, including Lympne–Beauvais. An identity card would be issued in lieu of a passport and the experiment was to run from Easter to the end of September 1959.
