abstract="Although Japanese National Railways had since 1966 had a universal Automatic Train Stop (ATS) system it was confronted with a few collisions resulting from enginemen acknowledging a stop signal and then proceeding. The new ATS-P system, in use on 40 km of the Kansai main line in 1980, will eliminate the acknowledging function so that no alarm will sound as long as the train is being properly operated. The new system consists of a receiving unit and a train-speed checking unit.<p />",
