In 2011, two locomotives of the company were equipped with MEP661 system and they are in-service today. The cost of this project would return in a short time, regarding the increased level of tractive effort, standby and traveling reliability.
 
There several advantages to the microprocessor system as below:
- The possibility to upgrade software and hardware 
- Improvement in the tractive effort and cohesion coefficient
- Maximum use of power for traction 
- Automated troubleshooting
- Possibility to lengthen time intervals between due services 
- Increased standby and traveling reliability
- Accessibility and lower cost as compared to competing systems
