The overhauled DMU is now composed of two identical motor wagons. The auto-stop device manufactured by RIZ (Zagreb Radio Industry) has now also been built in.

Other railways

There are some units also existing on Serbian Railways, where the designated class number is class 712. A few units are in operation in Macedonia as well, with two of the units, named Heracleia and Skopje, serving the Heracleia Express on the Skopje-Bitola route. The 2 units are equipped with Wi-Fi internet, widescreen TV-s and a cafe bar. All the units differ from Serbian and Croat units by having 3 cars and a stronger Cummins engine, adapted for the mountainous Macedonian railways.
