Mainline electric locomotive 2ES7

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.
