Trains have gained immense popularity as a fast and efficient mode of transportation [...]

Cooperative control of high-speed trains can improve the safety and efficiency railway transportation. However, velocity distance overshoots in cooperative multiple is an undesirable behavior, which will lead to unsafe inefficient train operation. To address this issue, a predictive set point modulation approach for proposed. First, cyber-physical modeling presented. The longitudinal dynamic ch...

Passengers of high-speed trains might be exposed to relatively high sound levels, compared to those inside conventional trains. In particular, sound levels inside Chinese high-speed train compartments may reach values as high as 80 dBA. Because traveling times are usually substantial in China, a wider variety of social activities occurrs inside the trains and more noise related problems for pas...

Moving trains represent a voluminous mass of users moving at high velocities that require bandwidth (on demand). Existing solutions typically based on wireless technology alone cannot scale efficiently to provide for bandwidth to such fastmoving voluminous users. A new approach is proposed that facilitates dynamic provisioning, good scalability and efficient use of available bandwidth. The prop...

Railway capacity is not only the basic condition for the allocation of railway resources but also an index set for the evaluation of the usage of them. Sometimes the maximum theoretical results calculated according to the coefficient methodology for the capacity calculation of the Existed Chinese traditional railway (abbreviated as ECTR) would be less than those statistical results from the rea...

After the earlier technologies that offered satellite mobile services for civil and military applications, today’s specific antenna design, modulation techniques and most powerful new generation satellites also allow a good level of performance to be achieved onboard high speed modes of transport such as aircraft and trains. This paper reports the Eutelsat’s experience in the developing and dep...

Automotive telematics has become an important capability of high-speed rail systems, which are increasingly popular in the era of green technology. As train speeds increase, communications between devices on the train and devices outside the train encounter difficulties, and maintaining high quality communication is a major challenge. Moreover, handovers on high-speed trains occur more frequent...

Recently, bicycles are used as exercising machines and traffic vehicles. Planetary gear trains can be used as the transmission systems for bicycles. The purpose of this work is to propose a design methodology for the kinematic design of automatic gear transmissions with planetary gear trains for bicycles. First, applying the check list method (combining and extending methods), the design concep...

Analysis of the slipstream development around the high-speed trains in tunnels would provide references for assessing the transient gust loads on trackside workers and trackside furniture in tunnels. This paper focuses on the computational analysis of the slipstream caused by high-speed trains passing through double-track tunnels with a cross-sectional area of 100 m2. Three-dimensional unsteady...

Timetables are affected by scheduled waiting time (SWT), which prolongs the travel times for trains and thereby passengers. SWT occurs when a train prevents another train from running at the necessary speed. The SWT affects both the trains and the passengers in the trains. The passengers may be further affected due to longer transfer times to other trains. SWT can be estimated analytically for ...
