Abstract. The article deals with the transition zone from the ballast sub-basement to the artificial structure with different types of superstructures, as well as sections of the ballast track. It is given the analysis of observations of the process of accumulation of residual deformations on the approaches to artificial structures.

Abstract. In article the problem of interface of bridges with ballastless designs of a railway track and approaches to them is considered. The most widespread structures of sites of the transitional rigidity are defined and it is offered the new, including application of a complex method stabilization of soils of the main platform of a subgrade and a ballast prism on the way to the bridge.
Comparison of the work of rubble-cleaning machines with one and two cutting devices
Keywords: crushed stone machine, cutting device, power, power consumption.

Abstract. In recent years, the network of Russian railways in the ICP has significantly increased the volume of the old-fashioned rail-grating on a reinforced concrete base, obtained from dismantling from the sites of modernization and major repairs of the track.
The main ways for more than 10 years have been transferred to a reinforced concrete base, with the accumulation of rail grating at disassembly of the track. This raises the question of the expediency of the further use of the links of the rail grating at the sections of the capital repair of the 3-5 grade road. The trend of recent years shows an increase in capital repairs on old materials, while increasing the needs of the transferred rail grating one of the main issues is to ensure its quality, in which the balance holders are interested, in the person of distance paths. With the increase in the volume of repair of the rail grating, the question of mechanization and automation of this process comes to the fore.
In this article, a description of the link repair facility PMS-216 st. Karasuk, the main advantages have been identified, a technical and economic comparison of two technological processes for dismantling the old-school RSP with reinforced concrete sleepers (on the template path and a new production line) on the production base of PMS-216 has been singled out.
Deformations of the road bed at Vorkuta distance

Abstract. The article presents the results of the materials of the study of deforming sections of the roadbed on the Khanovei—Yun-Yaga distillery conducted by the staff of the Khanovei scientific landfill and the comparison of these materials with the data of the survey of the personnel of the Vorkuta track. The obtained results allow to predict the condition of the roadbed, to develop a set of measures for its stabilization.
