Croatia: The HŽPP national passenger operator has awarded Končar a contract for the supply of 7 three-car 7023 series DMUs. The new trains will be able to reach a max speed of 120 km/h. Its passenger capacity will be 342 people, including 167 seats. As to Railway Gazette, Končar has produced 39 trains for HŽPP, including 5 such diesel trains and 34 electric trains of 6112 series, since 2011.
The new contract is being financed by a €31 mln loan from the Eurofima finance company. The first diesel train is scheduled to be delivered to the operator in two years. According to HŽPP CEO Željko Ukić, 63% of railway lines in Croatia are not electrified, which opens up potential for future DMU orders. Funding for promising contracts, along with projects to modernize the depot, is included in the 2021-2027 national program to increase competitiveness and cohesion.
Also, HŽPP recently announced plans to purchase two battery train prototypes from Končar worth €13.3 mln. The funding is to be obtained from the National Recovery and Resilience Plan. This will provide Končar with the opportunity to expand its range of low-floor regional passenger trains.

The first 7023 series DMU was produced by Končar in 2015 as part of a contract for the supply of 10 trains. The train was required to be as unified as possible with 6112 series EMUs produced by the manufacturer since 2011. After successfully passing all the tests, the train was put into permanent operation on the Zagreb-Varaždin line in February 2016. However, further deliveries were suspended due to lack of funding. A new order for the supply of 4 more trains was placed in 2018, the World Bank provided a loan for the purchase. The trains were put into permanent operation in 2019-2020.

The total length of the train is 58.5 m along the the automatic couplers. The trains are equipped with four 1,300 mm wide doors on each side for quick boarding and passengers alighting. The floor height is 600 mm above the level of the rail head, the passage through the train is stepless, except for the front part of the cabin, which is located above the motor bogie. The interior is equipped with a modern heating and air conditioning system, there are sockets under the seats, as well as free Wi-Fi. On the roof of the head cars there are two diesel engines manufactured by MAN with a capacity of 390 kW each. The transmission is electric, electrical equipment is manufactured by the Končar group. The power on the wheel rim is 690 kW, the design speed is 120 km/h, the acceleration is claimed to be up to 0.7 m/s2.
