Lessons for Policy Makers in Non-High Speed Rail Countries: A Review
High speed intercity passenger rail is an inherently strong railway application. It operates over 250 km/hour. For perspective, high-speed represents the ultimate development of preexisting standard gauge infrastructure. Network of high-speed passenger rail lines aimed at reducing accident, reducing traffic congestion, air pollution cutting national dependence on foreign oil and improving rural...
متن کاملImproved performance of subballast stabilized using geocell for high speed train
Rapid urbanization and growing industrial demand in many developing countries has led to frequent congestion of the transport infrastructure. Therefore, the expansion of high-speed rail (HSR) networks is crucial to meet this growing demand. Nevertheless, applying high cyclic stress causes significant lateral spreading and in turn excessive settlements of the track substructure. This problem bec...
متن کاملRail Damage Potentials of Sloshing Cargo
In this paper a two-degree-of-freedom model representing the sprung mass and the sloshing cargo in a vehicle is proposed to study the dynamic interaction of a sloshing cargo and the carrying vehicle, to simulate the dynamic wheel forces on the rails as a result of lateral perturbations derived from turnings along the railway path and the resultant cargo sloshing. The use of the Fourth- and T...
متن کاملStudy on different solutions to reduce the dynamic impacts in transition zones for high-speed rail
One of the most important factors influencing the track maintenance is the transitions between parts of the track with different vertical stiffness. The dynamic...
