On the newer high-speed trains, there are storage areas at one end of each train car, often across from the bathroom, which are available for anyone in that car to use for their larger bags. On the older trains, the only real storage areas are overhead shelves above the seats.

On Trenitalia’s high-speed Frecciarossa and Frecciargento trains in 2026, you have three main options for large luggage. First, there are large racks located at the ends of each carriage (near the doors) specifically designed for oversized suitcases. Second, most trains have a "V-shaped" space in the middle of the carriage where back-to-back seats meet, which can accommodate medium-to-large bags. Finally, for smaller items or thin large cases, there are overhead racks above the seats. In 2026, Trenitalia has also partnered with "Stow Your Bags" to offer automated locker services at major stations like Roma Termini and Milano Centrale for those who want to explore the city without their gear. For security, it is highly recommended to keep your luggage within your sight or use a small cable lock if you are storing it in the racks by the door, especially during stops at intermediate stations.
