The Sm3 Pendolino (originally branded as Pendolino S220, and usually referred to simply as the Pendolino) is a class of high-speed body-tilting trains operated by VR Group. It is a member of the Pendolino train family; its design is based on the ETR 460. The first two trainsets were assembled in Finland by Rautaruukki-Transtech in the mid-1990s. The rest of the series of eighteen EMUs were built by Fiat Ferroviaria (later Alstom) between 2000 and 2006. The trains serve most of Finland's major cities such as Helsinki, Turku, Oulu and Joensuu with a maximum speed of 220 km/h (140 mph), although this speed is only attained between Kerava and Lahti. The train has a power output of 4,000 kW (5,400 hp) and weighs 328 tonnes (323 long tons; 362 short tons).

The Sm3 had a long prototype phase before the main series was ordered, with reliability issues being brought up by the press from time to time. Negative reporting continues to haunt the series' reputation. Reliability problems cannot be proven, as no statistics of specific train types are available. The train has not managed to cope with harsh Finnish weather conditions, and the time benefit of the tilting mechanism has not be taken into account since the timetables of winter 2011–2012. Nevertheless, the Sm3 has also received positive feedback from passengers and has led to increased operating speeds on the Finnish rail network.
