Rijeka is integrated into the Croatian railway network and international rail lines. A fully electrified railway connects Rijeka to Zagreb and beyond towards Koprivnica and the Hungarian border as part of Pan-European corridor Vb. Rijeka is also connected to Trieste and Ljubljana by a separate electrified line that extends northwards from the city. Rijeka has direct connections by daily trains to Vienna, Munich, and Salzburg, and night trains running through Rijeka. Construction of a new high performance railway between Rijeka and Zagreb, extending to Budapest is planned, as well as rail links connecting Rijeka to the island of Krk and between Rijeka and Pula.
