In North America, railway freight traffic has increased nearly 30% over the past 10 years, and this demand is projected to increase 88% by 2035. It is clear that network capacity has to be increased by a combination of several engineering options, but the question is how railroads can allocate investment in infrastructure in the best po...

The practice of construction and operation railroads in the Arctic zone shows that greatest share track deformations occurs summer period during transition soils subgrade from frozen state to thawed state. Wetting, freezing-thawing, vibrodynamic effects trains have influence on properties clay composing railroad bed. A model a sub-tie base stabilized by geosynthetic materials is given. material...

This paper studies the systemic importance of railroads through the widespread holdings of their bonds by American fiduciary institutions during the Great Depression. We examine the impact of a series of large railroad bond prices shocks using a remarkable data set of the individual bonds held by each Massachusetts savings bank annually. We suggest that the shocks varied across banks for reason...

Ein wesentliches Medium Vermittlung von Konventionen Gestaltung dieses Geländ...
