Diesel locos class 754
Realization: 2008 – 2013, CZ LOKO, DPOV
Operator: ČD (Czech Railways)
Dieselelectric locos class 754 were produced by ČKD Praha in the end of 1970′s. They were designed for fast train operation on non-electrified lines.
The MSV elektronika’s control system replaces the original analogue traction regulator and automatic speed control. It also provides the possibility of multiply traction control or operation with driving trailer. The intervehicle communication according to NVL standard is prepared for installation of WTB gateway to communicate according to UIC 556.
The control system also controls the heating alternator and battery charging. The control system consists of control computer MODURAIL CRV DPV 7XX and the box of power outputs MODURAIL_NR5_754.
The man-machine interface uses 8,4″ LCD driver’s displays type ZJS01, they display operational states, diagnostic and failure messages. Next, standard control elements and driver’s keyboards BKL02 are used.
The fuel is controlled by actuator with step motor SKM-SM32. The loco’s speed is measured by new sensors DAKO FE1.4, there are also new voltage and current sensors. During diesel start, the voltage is supported by module MODURAIL_NR2_754. The loco is fitted with LED headlights BKS02 and BKS02N/B.
