Abstract

An increase of train load limits leads to a growth of values of straight and reverse traction currents in traction power supply system. Rails that provide channelling of reverse traction current in direct current power supply system are exposed to electrocorrosion, an intensity of which increases at the growth of traction currents. The aim of the work is to develop an analytical model that will provide a numerical assessment of metal losses from rail base at various modes of electric rolling stock operation and different condition of rail line isolation.
