The locomotive computer allows the machine personnel to monitor via PC panels installed on the control stands, more than 50 different parameters of the main and auxiliary drives (divided into different groups and different display forms). In addition, the computer communicates with the machine staff via messages about the state of the locomotive (more than 90 different messages).
The locomotive is equipped with a new digital data recorder in accordance with regulations and applicable standards. Ergonomics and driver’s cab comfort have been improved. There were installed new double headlights in LED technology produced by Gredelj.

The power of the traction locomotive has been increased by about 10% compared to the original locomotive in different operating conditions, with much greater reliability, with reduced fuel consumption and increased comfort.
