2ES6/3ES6 DC freight mainline electric locomotive/ DC freight mainline electric locomotive with a booster section
2ES6 “Sinara” two-section freight DC electric locomotive is designed to haul freight trains on 1,520 mm gauge railways electrified with 3 kV direct current voltage.
It is capable of hauling a train weighing 8,000 tons in sections with a flat track profile (up to 6 ‰) and a train weighing 5,000 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
Independent traction motor excitation allows to improve antiskid properties and expand parameters of tractive effort regulation.
