Abstract Railroad transport has a leading position in the country’s transport network. Similarly to land transport, rail wheels do the following: braking, rolling, and load transmission. The reliability of a wheel-rail system has a direct impact on the traffic safety. Major energy losses in the mechanical part of a rail-mounted locomotive account for the wheel-rail contact region. Hence, the wheel/rail interface is considered fundamental to the performance of railroad transport. The article considers the results of studies of the distribution of the magnetic field between the wheel and the rail, the criteria for evaluating the efficiency of magnetization of the wheel-rail contact zone. It was found that the saturation of the contacting surfaces of the wheel and rail occurs in different ways. For the saturated state at the two-point comb contact, the greatest value of the magnetic field induction on the crest is less than the induction on the riding surface. For the saturated state in the presence of an air gap between the wheel crest and the rail, almost all the magnetic flux is redistributed to the surface of the wheel.
