With the construction of high-speed railway lines in China, there are growing concerns about the rational transport cooperation between high-speed railway lines and conventional rail lines. A rational transport cooperation scheme can improve railway capacity utilization, train speed, service and the organization quality of railway transportation. The previous research mainly focused on the aspe...
Traction power supply equipments are the core part of the high-speed railway, so the maintenance of the power supply system is crucial for the security of the railway. Based on the research on the durable years of the traction power supply equipments, this paper puts forward the model of testing the traction power supply equipments of the reliable high speed railway. Some practical researches h...
This paper summarizes and analyzes the details of the control technology of the noise of High-speed Railway and the effects of its application, The situation data of the environmental noise of Beijing-Shanghai High-speed Railway is obtained by field monitoring. The results show that during the stage of trial run of BeijingShanghai High-speed Railway, under the condition of the normal traffic fl...
At present, there are few research results on the seismic response of track system railway suspension bridges, and relevant has not yet formed a certain standard. In order to provide reference for development industry standards design seamless lines based large-mass method multi-point excitation, taking China’s longest high-speed bridge-Wufengshan Yangtze River Bridge as engineering background,...
A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, and pressure to cooperatively pass their data through the network to a main location. It provides a bridge between the real physical and virtual worlds. The more modern networks are bi-directional, also enabling control of sensor activ...
Over recent years, Portugal has been working towards their integration in the trans-European high-speed railway network. While in Spain several new high-speed lines are already under construction or beginning operation, in Portugal the necessary studies are still being carried out. One of these studies concerned the location of one of the high-speed railway stations to be built in the city of P...
This paper studies the feasibility of using low-power wireless technologies such as Bluetooth, IEEE 802.15.4 and ZigBee in high-speed railway scenarios that involve bidirectional land-to-train communication. The presented results have been obtained through experimental tests conducted at the high-speed railway line connecting Madrid to Barcelona. A multiplatform communication system has been in...
The following paper discusses different aspects of railway bridge dynamics, comprising analysis, modelling procedures and experimental testing. The importance of realistic models is discussed, especially regarding boundary conditions, load distribution and soil-structure interaction. Two theoretical case studies are presented, involving both deterministic and probabilistic assessment of a large...
