  • C30-MC30-M

    The class C30-M locomotive is designed for heavy shunting and line service on lines and sidings with a 1520mm gauge. The six-axle diesel locomotive with an axle load of 23 tons features electric AC/DC power transmission. The locomotive is designed as a hood unit type with a cab tower installed closer to the rear face of the main frame. Its wheelset arrangement is C'o C'o and the vehicle’s maximum speed is 100 km/h. The locomotive was created by a complex modernization of the original class C30 locomotive (or derived types).

    The main frame is mounted on two three-axle bogies, between which a fuel tank is located. The drive unit is mounted on the locomotive in the front hood. It consists of a Caterpillar 3512C diesel engine and a Siemens auxiliary traction alternator. The auxiliary alternator is powering electrically driven auxiliary drives (compressor with a cooler, traction motor cooling fans, etc.). Both of these machines are combined in one unit and through a common intermediate frame are mounted on the main frame of the locomotive. The power transmission from the engine to the powered wheelset is electrical, AC/DC and comprises a traction alternator, a rectifier and six original traction motors. The traction motor is individual for each wheelset, on which it is mounted using bearings. The front hood space includes most of the auxiliary drives, engine cooling block and a pneumatic unit. The rear hood space includes electric switchboards and two electro-dynamic brake (EDB) blocks. The power output control and the control of the entire locomotive is ensured by the electronic control system. The locomotive is fitted with three DAKO pneumatic brake systems, a mechanical hand brake (parking) and an electrodynamic brake.
