The Kuna 87m ($US 13.9m) contract comprises Slnps flat wagons for Swietelsky, and Smnps intermodal flats for Eurailpool, co-owned by Swietelsky.
This follows an earlier contract with the Croatian company for Eamos tippler wagons which were delivered in 2010.
Duro Daković Special Vehicles will design both models of wagons in 2018, before building the prototypes for TSI testing and certification. Serial-produced wagons should be delivered in the second half of 2019.
Both types will be used for rail infrastructure traffic. The Smnps accommodate six containers.
