LTE Downlink Performance in High Speed Trains
2015 IEEE 81st Vehicular Technology Conference (VTC Spring), 2015Long Term Evolution (LTE) is expected to substitute the Global System for Mobile Communications (GSM) as the radio access technology for railway communications. Recently, especial attention has been devoted to high-speed trains since this particular environment poses challenging problems in terms of performance simulation and measurement.

Stability of high speed trains
Physics in Technology, 1973Recent developments in the understanding of the lateral dynamics of railway vehicles are reviewed with particular reference to the problems of dynamic stability, guidance and response to track features. The emphasis is placed on the physical models used and the broad conclusions they lead to, rather than the engineering design that represents the ...

Noise in the passenger cars of high-speed trains
The Journal of the Acoustical Society of America, 2015The aim of this study is to investigate the effects of both room acoustic conditions and spectral characteristics of noises on acoustic discomfort in a high-speed train's passenger car. Measurement of interior noises in a high-speed train was performed when the train was operating at speeds of 100 km/h and 300 km/h.

Broadband wireless communications on high speed trains
2011 20th Annual Wireless and Optical Communications Conference (WOCC), 2011This tutorial paper provides a comprehensive overview on the recent development in broadband wireless communications for high speed trains. Starting with the introduction of the two-hop network structure, radio-over-fiber (RoF) based cell planning is described in detail.

A Testbed for Evaluating LTE in High-Speed Trains
2013 Euromicro Conference on Digital System Design, 2013LTE is expected to substitute GSM as the basis technology for railway communications. Recently, special attention has been deserved to HST as this particular environment (mainly due to the high speed condition) can severely impact wireless systems performance. Although several channel models have been derived during the few last years, most of them are

Journal of Fluids Engineering, 1939
Abstract The purpose of this paper is to outline the changes which have occurred during the last five years in high-speed passenger-train cars and in motive power for hauling them and the economic factors which have brought about these changes. The new designs for passenger cars and the materials used in their construction are discussed.

IEE Colloquium on European Directives - Their Impact on Systems Engineering, 1996
EU directives are aimed at removing barriers to trade. Many existing directives emphasise safety issues because national safety regulations have often presented barriers to trade. However it is to be expected that as technology develops directives will need to address fundamentally new issues rather than merely regularising existing arrangements.

Distributed Cooperative Control of a High-speed Train
2019 American Control Conference (ACC), 2019The distributed cooperative control problem for high-speed train is investigated in this paper. Cars in a high-speed train are modeled as a group of ordered particles connected by flexible couplers. Each car is viewed as an intelligent agent that communicates with its neighbors, making the train a multi-agent system.

The analysis of high-speed wheel-rail train and high-speed maglev train safety systems
Proceedings of ICSSSM '05. 2005 International Conference on Services Systems and Services Management, 2005., 2005The high-speed wheel-rail traffic system was built in the 1960's, and then the relative technology was continually innovating. At the same time, the maglev experiment lines were built in Germany and Japan. The first high-speed maglev traffic commercial railway line in the world was built in Shanghai of China in 2003.
