what is it?
The E5K and ES5K (Russian: Э5К, ЭС5К, named "Ermak", Russian: Ермак) are a family of Russian mainline freight AC electric locomotives with a voltage of 25 kV, featuring four-axle units equipped with collector traction motors. Different versions: E5K, 2ES5K, 3ES5K, 4ES5K — are distinguished by the number of units according to the prefix (2, 3, 4 — number of units, E — electric locomotive, S — sectional, 5 — model number (5th series), K — collector traction electric motors). These locomotives are the next evolutionary step in the development of the VL80 family of freight electric locomotives and are positioned as their main replacement.
