Tootbus, RATP Dev’s subsidiary that operates sightseeing bus tours, has partnered with Eurostar to offer tourists the chance to explore Brussels (Belgium), London (England), and Paris (France). By offering a 20% discount on Tootbus tours for passengers who traveled on a Eurostar train, the two companies are demonstrating their shared desire to be more than just transporters of passengers, but rather full-fledged players in the discovery and promotion of cities.
