TRAIN HEADWAY OPTIMISATION USING VIRTUAL BLOCKS

TRAIN HEADWAY OPTIMISATION USING VIRTUAL BLOCKS

Although the implementation of a new Automatic Train Protection (ATP) system increases the safety level, it also exerts some impact on the blocking time in block sections, and consequently, on the headway between trains. At the same time, ATP systems introduce a train positioning system based on odo...
