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. The passenger compartment of the train was fully air-conditioned, and each set also included a buffet car.^[1]

Their main use in Yugoslavia was on lines Zagreb - Split - Zagreb, Zagreb - Zadar - Zadar - Zagreb, Zagreb - Šibenik - Zagreb and Zagreb - Osijek - Zagreb. They are also well remembered covering inter-city and fast services on the route Zagreb - Zabok - Varaždin - Čakovec - Zagreb, where they have spent the last 10 years of their active career. HŽ series 7 021 was withdrawn from service on January 10, 2005.^[2]
