The paper considers a new doubly-fed freight electric locomotive taking into account the world experience of locomotive construction, the regulatory base and operating conditions on the railways of Russia. Its parameters are presented: the main technical characteristics in comparison with currently used electric locomotives of new series, standard traction characteristics, and the characteristic of electric braking. Features of the design of the units and parts of the undercarriage and brake equipment are given. The studied doubly-fed freight electric locomotive is designed taking into account the optimal combination of equipment backup capabilities and increased operational reliability with minimization of the failure flow causing the withdrawal of two or more traction axles due to the faults. It has promising possibilities for replacing outdated locomotives with alternating and direct current, operated on sections with changing and adjacent stations, electrified on a constant and single-phase alternating current in the places where such sections are joined to the extent of the organization of traffic control according to the principles of working domain technologies. In this case, the joints between the two types of the train current can pass nearly without stopping, their running time is shortened, and the performance indicators are improved.
