Rail corrugation is a common railway defect that involves diverse and complex factors. grinding also the most commonly used method to address corrugations. Through numerous irregularity tests one-third octave frequency spectrum analyses, this study determined characteristics development process for rail on high-speed tracks. The vibration transmission properties of train were tested using force...

Travelling safely and comfortably on high speed railway lines requires excellent conditions of the whole railway infrastructure in general and of the railway track geometry in particular. The maintenance process required to achieve such excellent conditions is largely complex and expensive, demanding an increased amount of both human and technical resources. In this framework, an optimal schedu...

With the rapid development of high-speed railway (HSR), many scholars have studied competition between HSR and aviation or inter-city coach, but few studies discussed supply-service relationship within system. This paper explores cooperation conventional (CR) at city-pair level 39 core cities in China from temporal perspective. Comprehensive considering departure time arrival city pairs as repr...

This paper is devoted to developing a line-planning approach for high-speed railway networks merging newly built lines, which result in the change of network’s original structure and some passengers’ travel routes. In order exactly describe choice time-varying passengers operation trains, passenger network with time information constructed based on pre-generated candidate train set. Following t...
