Mainline electric locomotive 2ES10 “GRANIT”

2ES10 Granit freight two-section electric locomotive with induction traction motors is designed to drive freight trains on 1,520 mm gauge railways electrified with a 3kV direct current voltage.

2ES10 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 AG induction traction drive integrated in the structure of electric locomotive based on traction converters with IGBT transistor modules, which provides a significant increase of time between repairs and also increases traction.
Advanced system of on-board diagnostics provides data transmission via a dedicated radio channel to servers of transportation control center and repair enterprises.
To increase traction properties of 2ES10 freight electric locomotives, the BOOSTER SECTION was developed aimed at driving trains of increased weight along sections of railways with a particularly complex track profile.
System of automatic driving of electric locomotive according to a given parameter of the driving time with constant tracking of the locomotive's coordinates in space using GPS/GLONASS systems.
Modular cabin with improved ergonomic and hygienic parameters.
Reduced specific electricity consumption compared to 2ES6 electric locomotive due to use of technical solutions and energy-saving lighting.
