Abstract

An on-board train positioning and train integrity system combining inertial sensors and tachometer generators has been developed to detect train position and presence in a section using a radio train control system. In this system, curves and slopes which are registered as distinctive points on the track in an on-board database are used to detect train position and calculate train length. Additionally, train splitting can also be detected by the difference in acceleration between the head vehicle and the tail vehicle. Running tests using fail-safe processors equipped with these functions have demonstrated the feasibility of this system.
