Development of a Train Approach Alarm for Lines without Track Circuits

The TC type train approach alarm, which detects trains by track circuits, is widely used by JR East as a device to announce train approach. However, it had not been introduced to lines without track circuits, such as those with semi-automatic block systems. Therefore the authors developed a new train approach alarm that estimates train and worker positions by global positioning system (GPS), transmits train positions by mobile phone and licensed mobile radio, and emits an alarm to notify according to the approach distance of trains. The authors will work on introducing the alarm to applicable lines in future.
