The deployment of Kavach 4.0 is expected to significantly improve passenger safety and operational reliability, particularly during low-visibility weather conditions like fog and rain. It will minimise risks associated with Signal Passed At Danger (SPAD) incidents and ensure smoother train schedules. However, passengers may experience minor delays during the installation and testing phases, as technical blocks and speed restrictions are implemented. These disruptions will be carefully managed during lean traffic hours to minimise inconvenience.
