The article is devoted to the description of the variant of the traction energy system of alternating current of the double-track section of the electrified railway. The feature of the considered option of system is transmission of energy to electric trains by the increased tensions of two face values of 55 kV and 110 kV at the same time. The transmission of energy through the traction network to electric trains is still transmitted by a voltage of 25kV. The expected effect of the implementation of such a system is to provide a nominal voltage level in the traction network under the conditions of intensive high-speed and freight traffic, possible increase in the distance between the traction substations, significant reduction in electrical energy losses in the power supply system, reduction of the inductive and electrical influence on adjacent devices, decrease of the inductive resistance of the traction network. The possibility of a phased construction of the power supply system during electrification of the site, the capacity of which is adequate to the increasing current loads, is considered. At the same time, each of the stages can be considered as a separate version of the system.
