Due to constantly growing requirement increase in capacity of the existing network railroads of the Republic of Kazakhstan and (especially areas bordering with Russian Federation and China), the relevant issue is to improve the safety of operation of freight trains of increased mass and length. Putting into operation of heavy trains – the complex task connected with use of more powerful locomotives, increase in axial loadings, reconstruction of traveling infrastructure and power supply, improvement of technology of transportation process. In addition, increasing the speed of train traffic with increasing traffic density requires increasing strength and compliance paths. Technical policy of Joint-Stock Company National Company Kazakhstan Railways in Kazakhstan aims to complete the transition to a continuous path on a concrete base. This paper presents the results of measurements of the edge strains and stresses in the rail web in the center of the sleeper box outer rail of the filament curve of radius R = 380 m, obtained during testing of freight wagons and locomotive on the section of the railway line Almaty-Shu. The results of measurements of edge stresses and tension in the neck of a rail in a curve radius R = 380 m, obtained during the tests on the effect of the locomotive CKD6e-2108, freight cars 12-9941 and 12- 9920, on the section of the Almaty-Shu railway line are presented. The dependences of stresses in the edges of the sole and in the neck of the rail on the speed of the test rolling stock are obtained. The possibility of increasing the weight norms of freight trains without the cost of reconstruction of the track infrastructure is substantiated by introducing a fleet of modernized freight cars with an axle load of 245 kN (25 tons).
