2ES7 AC freight mainline electric locomotive
2ES7 two-section freight AC electric locomotive is capable of hauling 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‰).
The electric locomotive may operate in a system of multiple units, and autonomous operation of one section of the electric locomotive is also possible.
Advantage
Reduction of specific energy consumption for train hauling by 15-20%
