VSOE runs services between March and November. The classical London - Paris - Milan - Venice (and return) route via the Simplon Tunnel was altered in 1984 to serve Zürich, Innsbruck and Verona through the Brenner Pass. This journey is offered once or twice a week, depending on other trips. Two or three times a year Prague or Vienna and Budapest are also accessed, starting from Venice, and returning to Paris and London. Every September the train also travels from London and Paris to Istanbul via Budapest, Sinaia and Bucharest - in the last three cities a sightseeing tour (and in the two capitals an overnight stay in a hotel) also takes place - the return trip on the same route ends in Venice.
