Sinara (2ES6, 3ES6)

Description Advantage Specifications

Freight electric locomotive fitted with commutator traction drive and a contactor-rheostat starting system is intended for hauling freight trains on 1,520 mm gauge railways electrified with 3 kV direct current.

Able to haul a train weighing 8,000 tons on sections with a plain track profile (up to 6 0/00) and a train weighing 5,000 tons on sections with mountainous profile (up to 10 0/00).

New design solutions improved the technical specifications of the electric locomotive, reduced operating costs, increased reliability and safety of the electric locomotive in comparison with previously created locomotives:
•  10-15% less energy consumption;
•  15% less repair hours;
•  improved working conditions for locomotive crews;
•  50% more maintenance intervals;
•  enhanced average daily productivity through increase of weight limit by 25-45%.

Electric locomotives are operated on the transport network and regularly undergo warranty and after-sales service.

Currently, 1,500+ Sinara electric locomotives of the 2ES6 and 3ES6 series are in operation.

Advantage

The microprocessor control system of MPSU and D includes auto-driving functions with the ability to transfer control to operators of remote stationary control centers, diagnostics, data transmission via technological radio communication channels, parameter registration, GPS/GLONASS positioning
During the development, for the first time, independent excitation of traction motors was successfully applied, which made it possible to improve the process of realizing the thrust force
It is possible to operate an electric locomotive according to a system of many units, as well as the autonomous operation of one section of an electric locomotive
Improved technical speed indicators, which increases throughput without investing in infrastructure
The working conditions of locomotive crews have been improved
The BLOCK system ensures traffic safety
