It’s not actually possible to travel from New York to Italy entirely by train, because the Atlantic Ocean separates North America and Europe—there’s no rail connection between the continents. If you’re asking theoretically, a “train-only” journey would require impossible links (like a transatlantic rail tunnel), so there is no real travel time by train. In practical terms, the fastest way to make this trip is by plane, which takes about 9–11 hours of flight time, or around 11+ hours total including transfers. 👉 Bottom line: You can’t go from New York to Italy by train; you’ll need to fly (and possibly use trains only within Europe after arriving).
