Yes, bringing suitcases on European trains is standard practice, but the rules are more flexible yet physically demanding than air travel. Unlike airlines, most European operators (such as DB, SNCF, or Trenitalia) do not charge for luggage and do not have strict weight limits, provided you can carry the bags yourself and store them in the designated areas. Most trains feature overhead racks for medium bags, "A-frame" racks between seat backs for larger suitcases, and large luggage stacks at the ends of the carriages. However, certain high-speed services like Eurostar have a nominal limit of two large suitcases (up to 85cm) and one piece of hand luggage per person. Low-cost rail carriers like Ouigo in France or Avlo in Spain operate more like budget airlines, where only one small bag is free and larger suitcases require a pre-paid fee. A key tip for European rail travel is to pack light enough to lift your bag onto the train's steps and into overhead racks, as many historic stations lack elevators.
