The unintended vibrations and sound emerging from train operation have an enormous impact on the surroundings, including deterioration of way, buildings, structures. One proposed strategy to mitigate this issue is installation a rail pad inserted between steel concrete sleeper provide flexibility track cushion shocks generated by wheels’ movement. These materials nonlinear, dissipative properti...

The shear resistance at the sleeper–ballast interface of a ballasted track is an important contributor in maintaining stability under faster and heavier axle loads where ballast undergoes significant lateral sliding. Different types interfaces based on type sleeper arrangements, such as concrete sleepers, timber pads (USPs) attached to sleepers influence railway tracks. Therefore, this study de...

To date, the spring stiffness of resilience pads was mostly evaluated based on conventional (site measurement and laboratory tests) methods. Most studies in past analyzed effects deterioration track damage. examine pads, evaluations were conducted tests using site measurements samples collected from site, or loading special equipment. such as TSS. However, no methodology proposed to prove theor...

The increased speed and weight of modern trains puts the components of a railway track in a highly dynamic load situation. Irregularities of the wheels and rails induce substantial dynamic loads that have to be accounted for in the procedure of designing the railway track. The concrete sleeper is an essential part of the track structure and there is a growing demand for improved analytical tool...

Major growth in rail traffic in many parts of the world in recent years has brought railway networks close to capacity and restricted the time available for track access to carry out maintenance work without costly temporary route closures. There are, therefore, significant benefits in designing or modifying ballasted track systems to reduce maintenance and associated access requirements. Under...

The control of vibration generated by railways in tunnels is complicated by the dynamic interaction between tunnel and track. Conventional methods (floating slab track, ballast mats, under-sleeper pads) do not perform as well as might be expected and it is the purpose of this paper to explore the sources of error. The major factors which must be taken into account pertain to the three-dimension...
