Scoping assessment of free-field vibrations due to railway traffic [PDF]
, 2018 The number of railway lines both operational and under construction is growing rapidly, leading to an increase in the number of buildings adversely affected by ground-borne vibration (e.g. shaking and indoor noise).

Improving lateral track strength after ballast maintenance
Railway SciencesPurposeMxV Rail conducted multiple single tie push tests (STPTs) between 2020 and 2023 to assess the changes in lateral tie resistance from tonnage accumulation, dynamic track stabilizers (DTS), tie type and ballast condition. High lateral tie resistance is necessary for preventing lateral misalignments and track buckles.

Numerical investigation of the behavior of approach slabs in transition zone of ballasted track to box culvert in high-speed railway lines [PDF]
Journal of Structural and Construction Engineering, 2016 One of the most important issues in operation of high-speed railway tracks is avoiding to sudden variation of the track stiffness. Culverts and bridges are common areas which this problem is occurred along the railway lines.
