High-speed rail systems are expanding everywhere for carrying thousands of passen-gers every day. Train cars in underground spaces travel under dense urban areas, tun-nels mountainous places and bridges across rivers. Design fire burning a train car should be studied carefully hazard assessment those long or en-closed spaces. There full-scale testing results on the main combustibles in-cluding ...

The definition of train scheduling is going to shift its current static approach, as generally resulting in a timetable, towards dynamic approach where the timetable can be modified order enhance satisfaction passengers’ demand. In this paper, demand-oriented and rescheduling models are formalized propose that satisfy groups passengers. More specifically, assessment based on min max method. pro...

Train-to-train communication will be the key technology for future railway operation. An increase of safety and efficiency can be achieved by exchanging data between trains via ad hoc networks. For vehicle-to-vehicle communication the European standard is intelligent transport systems (ITS-G5). The usage of this standard for railways is hardly investigated. We investigate the performance of ITS...

OBJECTIVE To analyze the status of occupational stress in different types of train drivers. METHODS By using cluster sampling method, a cross-sectional study was conducted in 1 339 train drivers (including 289 passenger train drivers, 637 freight trains drivers, 339 passenger shunting train drivers, and 74 high speed rail drivers) from a Railway Bureau depot. The survey included individual fa...

Train induced vibrations are a major environmental concern both in Europe and China. Besides the effect of vibrations due to passenger and freight trains and subways at relatively low speed, the study of the vibrational impact of high speed trains is of high interest. In Belgium, for example, new high speed train lines connect Brussels with Paris and London, while extensions to Amsterdam and Co...

The high-speed railway has become an important passenger transport mode. Relying on the abundant experience and expansive network, freight train (HSFT) is feasible to be developed great application potential. As a critical component of HSFT, cargo plays role in overturning safety HSFT under strong wind conditions. Previous studies about aerodynamic performance usually regarded loaded carbody as...
