Abstract
EN: Abstract. The problems of electric track circuits calculating were investigated in the works of various
authors, it is noted that there is no complete clarity on the definition of shunt resistance. The value of the
calculated train shunt resistance in many respects affects the area of signaling systems rail channel stable
operation and train traffic safety. It is relevant to study the possibilities of changing the standard value of
and the conditions for the execution of track circuits shunt mode, especially for sections of railway with
low resistance insulation of the rail line. The surface area of the “wheel-rail” skating, taking into account
the different conditions of interaction dynamics and wear of rails and wheel elements were obtained in
article. It is shown that the reduction of the normative value of the resistance of the train shunt is
appropriate for signaling systems, especially for sections of railway with low resistance insulation of the
rail line. An approximate estimate of the geometric parameters of the membrane that forms on the “wheelrail”
surface is obtained; proposed a more complete electrical replacing scheme for the train shunt circuit,
which allows analyzing the influence of the circuit elements parameters values and the frequency of the
signal current. A method for calculating the correlation dependence of the train shunt resistance from
wheel-rail surface membrane parameters is proposed.
