The railway networks in Canada traverse from coast to coast, and pass over diverse terrain with large stretches of very soft soils, including clay deposits and peat formations. The majority of these lines were constructed approximately 100 years ago. Railway loads have since increased...
Collisions of motorized transport with wildlife impact a wide range of species and can cause injuries and economic losses to people. On roads, vehicle collisions with animals have been studied extensively, resulting in mitigation measures that reduce collisions by segregating animals and...
Landslide Risk to Railway Operations and Resilience in the Thompson River Valley near Ashcroft, British ColumbiaDownload
This thesis investigates the hazard frequency and associated risk posed by twelve large landslides in the Thompson River Valley south of Ashcroft, British Columbia, which are collectively referred to as the Ashcroft Thompson River landslides. The Canadian National and Canadian Pacific railways...
For railway track geometry to meet regulatory requirements under normal operating conditions, railway ballast must provide sufficient lateral resistance to control track deformations. This implies that on tangent tracks the lateral resistance of the ballast must be sufficient to resist thermal...
Linear features such as roads and railways threaten wildlife directly through collisions with vehicles. Although the adverse effects of roads on wildlife have been extensively studied resulting in widespread mitigation measures (e.g. fencing and highway crossing structures), far less attention...
