2TE25K diesel locomotive has been used as the basis of the 2TE25A class main line two-unit diesel freight locomotive of the same power rating and featuring AC/AC transmission and collector traction motors.^[2]

From 2017 to 2020, twelve triple-unit 3TE25K2M locomotives rated at 9,300 kW (12,500 hp) have been supplied. These are now the most powerful diesel locomotives on Russian railways.^[1]

In 2022, in response to International sanctions during the Russian invasion of Ukraine resulting from the Russian invasion of Ukraine, Russian Railways announced that it would cease production of 2TE25K locomotives.

The new 3TE28 [ru] locomotive, which doesn't use the American technology of the 2TE25K, began production in 2023.^[3]
