Stadler KISS Soko (“Falcon”). Train Belgrade–Novi Sad
The Stadler KISS is a family of bilevel electric multiple unit commuter trains developed and built since 2008 by Stadler Rail of Switzerland. As of 2016, 242 KISS trainsets comprising 1,145 cars have been sold to operators in eleven countries.
In the early stages of its development, the KISS was known as the Stadler DOSTO. This name was derived from the German word Doppelstock, meaning “double decker”.
Since September 2010, Stadler refers to the train as “KISS”, an acronym for “Komfortabler Innovativer Spurtstarker S-Bahn-Zug”, meaning “comfortable, innovative, sprint-capable suburban train”.
