The 3ES6 is a freight electric locomotive — a three-section DC mainline machine built to move heavy trains across electrified networks. Output figures define its class: 9,000 kW continuous power at the traction shafts (9,660 kW hourly) with tractive effort of 627 kN continuous and 696 kN hourly, at a design speed of 120 km/h.
Electric braking is equally serious — 9,900 kW regenerative capacity on the traction shafts plus 8,250 kW rheostatic — returning energy to the grid and saving brake wear on long grades. Static axle load stays within 25 tonnes per wheelset, fitting standard mainline track.
Locomotives of this category are fleet capital for national railways and industrial operators hauling coal, ore, containers and bulk freight. Procurement runs through project contracts covering gauge and systems adaptation, homologation, crew training and service support, agreed with the manufacturer.
The 3ES6 offers railway operators proven Russian freight-electric engineering with an established operating record.
