Quantification of rail seat load distributions on concrete crossties
As higher demands are placed on North American railroad infrastructure by heavy haul traffic, it is increasingly important to understand the factors affecting the magnitude and distribution of load imparted to concrete crosstie rail seats. The rail seat load distribution is critical to the analysis …

Hydraulic Mechanisms of Concrete-Tie Rail Seat Deterioration
Rail seat deterioration (RSD) is considered the most critical problem with concrete-tie performance on North American freight railroads. RSD is the deterioration of the concrete underneath the rail that results in problems such as wide gauge, insufficient rail cant, and loss of fastening toe load. …

Understanding the vertical load path under static and dynamic loads in concrete crosstie and fastening systems
… load path a lack of clear understanding of the loads on the components exists. A number of failure mechanisms of ties, pads, insulators and fasteners still exist. This study focusses on understanding how the stiffness of the components in the system affects the flow of forces in the vertical …
