There's no fee to bring luggage on the train. The on-board luggage storage options differ depending on the type of train. 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.

Yes, you can take a big suitcase on trains in Italy, but there are specific rules depending on the type of train and the class of service. On high-speed trains like Trenitalia's Frecciarossa and Italo, there is usually no official weight limit, but you must be able to lift the bag yourself into the overhead racks or the luggage areas at the end of the carriage. For Italo, the "Smart" class restricts luggage to dimensions of 75 x 53 x 30 cm, while "Prima" and "Club Executive" have more flexible space. Regional trains are more relaxed about size but often lack dedicated luggage racks, forcing you to keep bags in the vestibule or between seats. In 2026, it is a grounded tip to avoid oversized "hard-shell" cases if possible, as storage space can fill up quickly during peak tourist seasons. If your bag is exceptionally large (over 80cm), some private operators may require an additional small fee or "oversized" booking, so always check your specific ticket tier's "baggage policy" before you reach the platform.
