SŽ series 310 is a high-speed tilting EMU used on the InterCitySlovenija (ICS) premium train service in Slovenia, operated by Slovenske železnice. It is based on the Italian ETR 460 commonly known as Pendolino. The train is capable of reaching a maximum speed of 200 km/h. The train is electric single system - 3 kV DC. It is one of three high-speed train services in Central and Eastern Europe - the other two are located in Croatia (RegioSwinger) and the Czech Republic (ČD Class 680, also based on the Pendolino).
The ICS links the major cities of Slovenia in one line: Koper (only in summer), Ljubljana, Zidani Most, Celje and Maribor, with frequent service that acts as a high-speed shuttle. The train is made up of three cars: two 2nd class cars and one 1st class car. The trains provide disabled access, as well as a telephone and a snack bar. There is a smoking section in one of the 2nd class cars; the rest of the train is non-smoking.
The ICS reaches a maximum speed of 140 km/h on the section between Ljubljana-Zalog and Ljubljana-Polje stations.
Slovenske železnice bought three trainsets, two of which operate on the (Koper-)Ljubljana-Maribor route and one of which operated on the Ljubljana-Venice Santa Lucia route as EC Casanova. This service was discontinued in April, 2008.
