Due to its location in the centre of the Italian peninsula, Rome is the principal railway node for central Italy. Rome's main railway station, Termini, is one of the largest railway stations in Europe and the most heavily used in Italy, with around 400 thousand travellers passing through every day. The second-largest station in the city, Roma Tiburtina, has been redeveloped as a high-speed rail terminus. As well as frequent high-speed day trains to all major Italian cities, Rome is linked nightly by 'boat train' sleeper services to Sicily, and internationally by overnight sleeper services to Munich and Vienna by ÖBB Austrian railways.
