SŽ series 310 represents a tilting high-speed Electric Multiple Unit (EMU) deployed by Slovenske železnice on the InterCitySlovenija premium line since September 2000. Modeled after the Italian ETR 460 Pendolino, it operates under a 3 kV DC electrical system and achieves speeds up to 200 km/h.
This service links Slovenia's key urban centers—Ljubljana, Celje, and Maribor—offering frequent, rapid shuttle connections. The tilting mechanism enables travel at velocities reaching 160 km/h on track segments between Maribor, Pragersko, Slovenska Bistrica, Grobelno, and Sentjur. Each three-car formation contains two second-class coaches and one first-class coach, equipped with facilities for disabled passengers, onboard Wi-Fi, and a refreshment bar.
In 2000, Slovenske železnice procured three trainsets, all currently assigned to the Ljubljana–Maribor corridor.
One of these SŽ 310 units also operated international services as Eurocity 50/51 Casanova between Venice Santa Lucia and Ljubljana from December 2003 until April 2008. From December 2004 through December 2005, this route was extended to Maribor, featuring Intercity connections to Graz in Austria.
