Hi Lisa, you can bring a suitcase that fits the measurements below:

Height + Width + Depth = Less than 160 cm is OK.

Meassure the height + width + depth of your suitcase, if it’s less than 160 cm you’re free to bring it along on the train and use the normal baggage area and rackets on the train without a reservation with a normal tickets. Even on the non-reserved wagons.
