You're generally welcome to bring up to 3 pieces of luggage onboard, at no extra cost. These items may include satchels, backpacks, suitcases and the like. However, some train companies have different luggage policies, so it's always a good idea to check their website before you travel.

You can absolutely bring a suitcase onto a train, and in 2026, rail travel remains far more lenient than flying regarding luggage. Most major operators like Amtrak, DB (Germany), and Trenitalia allow at least two large suitcases and a carry-on for free. Unlike airlines, there are rarely strict weight limits, though the general rule is that you must be able to carry and stow your own bags without assistance. On high-speed trains like the TGV or Eurostar, there are dedicated luggage racks at the ends of each carriage and overhead bins for smaller items. Some low-cost European rail providers, such as Ouigo or Avlo, have begun implementing "airline-style" luggage fees for oversized bags, so it is crucial to check your specific fare type. In the U.S., Amtrak allows two bags up to 50 lbs each for free. The primary benefit of train luggage is the lack of "liquid restrictions" and the ability to keep your belongings with you, making it an ideal choice for travelers who prefer to avoid the hassle of checked-bag wait times and potential loss at airports.
