A Position Detection in Railway System

To safely control a group of trains, it is essential to detect the position of train. The system to detect the position of train by the train itself will become a mainstream of the new systems using radio transmission. This paper introduces the methods of train position detection that have been studied, introduces the trend of these methods. It also described the fundamental concept and approach to realize a system to detect the position of train which is applicable to systems.
