Scope of Application

The DC double-section electric freight locomotive 2ES6 SINARA is designed to haul freight trains on 1520 track gauge rail lines electrified at 3 kV DC.

The locomotive can haul freight trains with 8,000 tons on gradients up to 6 0/00 and trains with 5,000 tons on gradients up to 10 0/00.

The locomotive is designed for multiple-unit operation; however, single units may also operate independently.

Advantages of Class 2ES6 Locomotive

  • For the first time outside excitation of traction motors has been successfully applied in the design, which enabled to improve the wheel slip protection and the process of tractive effort realization expanded tractive effort control.
  • A microprocessor-based locomotive control system is installed.
  • The On-Board Diagnostics System provides messages to the driver, and transmits data via radio communication channels to Information Processing Centers and to the Locomotive Maintenance Depots.
  • The GPS/ GLONASS global positioning system and the automatic train operation system allow for handover of locomotive control to operators at Remote Control Centers.New to Russian industry, technical solutions lead to improved locomotive performance, lower operating and maintenance costs and a higher level of reliability and safety (compared to locomotives designed earlier):
  • Energy consumption is reduced by 10-15%;
  • Repair hours are reduced by 15%;
  • Improved working conditions for locomotive crews;
  • Maintenance intervals are increased by 50%;

Average daily performance is increased by 25-45 % due to a higher tonnage rating
