Two-section AC freight electric locomotive 2ES7 is capable of driving a train weighing 9,000 tons in sections with a flat track profile (up to 6‰) and a train weighing 6,300 tons in sections with a mountain profile (up to 10‰).

It is possible to operate an electric locomotive in a system of many units, and autonomous operation of one section of an electric locomotive is also possible.

Advantages

  •  Application of Siemens induction traction drive with axial torque control based on traction converters with IGBT transistor modules allows to implement traction force and significantly increase time between repairs.

  •  Application of MPSUiD microprocessor system with functions of auto-driving, diagnostics, data transmission via technological radio channels, registration of parameters, GPS/GLONASS positioning.

  •  New type modular cabin with improved ergonomic and hygienic parameters.

  •  High maintainability due to modular arrangement of equipment.

  •  Time between repairs is increased by 5 times.

  •  Reduction of specific energy consumption for train traction by 15-20%.
