The revolution of railway system by using advanced information technology

Introduces application examples of information technology as it is applied in several fields of the railway system, namely transportation and safety, service, maintenance and the Internet. This paper shows that safety, efficiency and convenience have been improved in the areas of railway use, operations and maintenance. This is followed by a section on a new train control system for high-density lines that uses methods for transmitting information to the train about the distance to the position at which the train must stop, which is necessary for train control. This system is realized through the advanced application of information technology. Until now, it has been impossible to realize efficient operations in high-density lines due to limitations of existing signal technology. However, this has now become possible with the new train control system. The paper introduces the information technology used in this system and future developments.
