Use

This series was used for high quality service travel, covering some of express or fast train lines in Yugoslavia and later in Croatia. It was arguably the most beautiful and most comfortable train on Yugoslavian and later Croatian Railways.

Their main use in Yugoslavia was between Zagreb and Split (Zadar and Šibenik), between Zagreb and Osijek and between Zagreb and Belgrade. From the mid-1990s, they started to serve fast train line Zagreb - Varaždin - Čakovec - Zagreb until 2005 when they were withdrawn from service.
