The high-speed train journey from Milan (Milano Centrale) to Zurich (Zürich HB) typically takes between 3 hours and 17 minutes and 3 hours and 50 minutes. This route utilizes the Gotthard Base Tunnel, which is the world's longest and deepest railway tunnel, allowing trains to bypass the steep mountain climbs of the Swiss Alps and travel at speeds up to 250 km/h (155 mph). Most services are operated by the "EuroCity" (EC) trains, which are a collaboration between Trenitalia and SBB (Swiss Federal Railways). These trains are modern, air-conditioned, and offer stunning window views of Lake Como and the Swiss countryside before plunging into the tunnel. In 2026, there are frequent daily departures—roughly one every hour—making it an incredibly convenient "city-center-to-city-center" alternative to flying. It is important to note that while the train is high-speed, the "Swiss" portion of the track through the mountains involves more curves and stops (such as Lugano and Bellinzona) than the flat Italian plains, which accounts for the variation in travel times depending on the specific service and number of stops made along the scenic trans-alpine route.
