The electric locomotive series 361 was created by extensive rebuilding from direct-current locomotive series 163 by installation of the second traction system and modernization of components. The traction chain is completed with newly-developed and manufactured traction transformer T1T-4900-25/2x1700, disconnectors, earthing devices, alternatingcurrent master switch, traction rectifier UN 3000/1410. Original pulse converters in the quantity of 4 pcs are replaced with two JR 3000/3000-720 pulse converters for power supply of traction motors, which have an increased power of 900 kW due to modernization.

An excitation of traction motors itself in the running – brake mode is provided by pulse converter of excitation of motors JR 3000/2x220-90.1. New control system MIREL RS 361 is installed in the locomotive, which provides the control of locomotive in all modes. Airconditioning units have been installed to driver cabs and it was created hygiene corner with hot and cold water, microwave oven, kettle and refrigerator in order to increase the comfort.
