Exploitation and technical characteristics

Diesel multiple unit is particularly suitable for exploitation on railway lines with high passenger frequency, on shorter commuter traffic distances, as well as for greater distances on non-electrified lines. It consists of two motor cars, each being equipped with a driver's cab and the possibility of control depending on the running direction. From one driver's cab it is possible to control three coupled sets of two-part DMU's. A two-part set can carry a total number of 288 passengers, out of which number there are 144 passenger seats. Maximum speed of DMU is 120 km/h. The auto-stop device manufactured by RIZ (Zagreb Radio Industry) has now also been built in.

Reconstructions and modifications

There are two subseries of these trains - subseries 000 and subseries 100 - subseries 100 were created in 1997 when the modernization of part of the sets by TŽV Gredelj began - the main difference between these subseries is that subseries 000 has both engines located in one trailer, while subseries 100 has one engine in each trailer. Also, the reconstruction during the creation of subseries 100 resulted, among other things, in a complete change of interior (replacement of the seats, wall panels, toilet facilities, etc.), and in partial change of exterior design on the front parts of the sets, as well as adding the side displays. In 2010, TŽV Gredelj also began to modernize the sets of the 000 series, which primarily included changing of the interior and only some minor modifications to the exterior, such as adding side and/or front displays. Also, 000 sub-sets that were reconstructed during 2020's also received air-conditioned interiors (passenger compartment) and some of thm even audio/video passenger information system.
