Abstract.

The paper analyzes operation of intermediate rail fastening in terms of operational conditions with intense freight traffic taking into consideration peculiarities of rail track performance within curvilinear sections of small-diameter curvature radii. Objective of the paper is to increase the operational life of intermediate rail fastening for their operations in terms of high speeds of train movement and within curvilinear track sections with extra small curvature radii with rail gage adjustment. It has been demonstrated that facilities and materials of both rail track and its components are subject to intense wear and breaking under considerable vertical and shearing loads, especially within curvilinear track sections with small curvature radii. Recommendations and initial technical requirements are given to develop long-range designs of intermediate rail fastening. Innovative engineering solutionis proposed for intermediate rail fastening providing 1520-1540 mm rail gage regulation for tight 200.0-600.0 m curves.  In this context, the design features make it possible to preserve optimum (i.e. estimated) position of holding-down hinges of elastic terminals as for vertical axis of rail symmetry as well as ends of rail bases, which improves functionality, durability, and reliability of rail fastening under the conditions of significant lateral dynamic loads. The new system of anchor intermediate fastening of АПРС-1 is proposed for rail tracks of railway, industrial, and underground rail transport to be used for trunk roads with operation life being up to 1.2 billion tons of passed gross freight, and 250.0-300.0 km/h speed; it is also acceptable for curvilinear tight 200.0-600.0 m radii with complicated operational environment, and up to 30 ‰ longitudinal gradient. The fastening system is foreseen to be used for open-pit rails under significant 30.0-45.0 t axial loading, and considerable (up to 60 ‰) longitudinal gradients with the use of traction facilities as well as for underground rail transport where rail width is 900, 750, and 600 mm, 8.0-20.0 curvature, and track widening up to 20.0 mm. The obtained results may be applied for railroad, industrial and underground rail transport.

Keywords. intermediate rail fastening, loading, wear, breaking, operational life.
