7021 series was a diesel-motor train on Yugoslav and later Croatian Railways built by French manufacturer Brissonneau and Lotz for Yugoslavia.

[weasel words] 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.

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.
