Onboard Sub-System receives and analyses the information about trackside status and characteristics of the movement authority sent by Eurobalise or by the Data Infill Unit. It calculates the dynamic speed profile in relation to the train characteristics which are already stored on-board and selects the most restrictive speed value to be observed at the locations ahead.
Moreover, it compares the train’s actual speed with the permitted speed and, if necessary, applies automatic brake. Display of indications and provision of alerts/warnings are provided to the driver.
