Some aspects are illustrated of energy conversion processes during the operation of electric railway vehicles with traction induction motors, in order to support transport systems’ sustainability. Increasing efforts are being expended to enhance the sustainability of transportation technologies and systems. Since electric drive systems are used with variable voltage variable frequency (VVVF) in...

The railway crossing accidents are increasing day by day due to unman railway crossings. This paper presents an automatic control gate system to prevent rail accidents. Pressure sensor, RFID card, Servo motor is used to control the open and close status of the railway crossing gate. In this paper we propose a model where pressure sensor is placed on the railway tracks, RFID tag on the engine an...

Progress of construction technology Japan has a relatively small proportion of lowland, consisting mainly of alluvial coastal plains. Railway construction started in the early Meiji Era (1868–1912) and since the construction technology was still immature, the first lines were built in level coastal areas. The rails were laid mostly on earth structures such as embankments and cuttings. Many rail...

As the world’s highest railway, and the longest highland railway, the Qinghai–Tibet Railway (QTR) has been paid considerable attention by researchers. However, most attention has been paid to the ecological and environmental issues affecting it, and sustainable ecological, social, and economic development-related studies of the QTR are rare. In this study, by analyzing the passenger traffic, fr...

BACKGROUND Workers in blue-collar and service occupations smoke at higher rates than workers in white-collar and professional occupations. Occupational stress may explain some of the occupational class differences in smoking and quitting behavior. The purpose of this study is to investigate the contribution of occupational factors to smoking behavior over a ten year period among a multiethnic c...

Multi-Agent based modeling & simulation is an evolving paradigm for solving real life problems for solving real life problems for the last one decade. In this paper, we model the manually controlled Indian Railway to a multi agent based automated system which is robust in nature and provide a fully automated collision avoidance guarantee. We consider individual entity such as station, junction ...

Guinea-worm infestation is prevalent in some sections of the Hubli Medical District of the Southern Railway. These sections are situated *n the civil districts of Dharwar, Bijapur and ^holapur of Bombay State. No cases are encountered among residents of railway colonies as no step wells are in use, but railway employees, especially engineering gangmen, who *jve in the villages adjoining railway...

This paper deals with disruption management in passenger railway transportation. In the disruption management process, many actors belonging to different organizations play a role. In this paper we therefore describe the process itself and the roles of the different actors. Furthermore, we discuss the three main subproblems in railway disruption management: timetable adjustment, and rolling sto...

GSM-Railways (GSM-R) is a communication mobile network designed to fulfill specific communication needs of railways. GSM-R is being widely deployed across Europe and other countries around the world for providing railway voice and train control services (ETCS). Despite that, GSM-R already shows various shortcomings in terms of capacity and support for additional data services. This triggers the...

The paper presents an innovative networked radar system for detection of obstacles in a railway level crossing scenario. This Monitoring System (MS) is able to detect moving or still obstacles within the railway level crossing area automatically, avoiding the need of human presence for surveillance. The MS is also connected to the National Railway Information and Signaling System to communicate...
