In order to rationally evaluate the high speed railway operation safety level, the environmental safety evaluation index system of high speed railway should be well established by means of analyzing the impact mechanism of severe weather such as raining, thundering, lightning, earthquake, winding, and snowing. In addition to that, the attribute recognition will be identified to determine the si...

The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...

Because of using the nonlinear high-power, single-phase, multi-step full wave or bridge rectifier electric locomotive in electrified railway, the electrified railway traction power supply system has serious power quality problems, which affect safe operation of the electrified railway and impact the local power grid adversely. Aiming at the electrified railway power quality problems, a homogeni...

Union Internationale des Chemins (UIC) defines the high-speed railway (HSR) as a system that contains infrastructure and rolling stock. The can be newly built dedicated lines enabled for trains to travel with speed above 250 km/h or upgraded conventional up 200 even 220 km/h. HSR requires specially increased power weight ratio must have an in-cab signalling traditional systems are incapable of

Erosion of the river banks in India have become recurrent event causing enormous problem for the people and the Government. With the increase of population along the bank of the rivers, the erosion of township, cluster of villages and important communication system, govt. resources are over exploited. Presently a large number of township, villages, human dwellings a number of important installa...

With the high speed railway speed increasing and driving distance shortening in China, the time conformity of subsystems of railway is becoming more significant to railway traffic safety. The railway time synchronization network (RTSN), the medium carrying and broadcasting time information, is responsible to convey the information of internal clock of railway and its function poses direct influ...
