Patiala, April 30 -- With two blasts in the last three months targeting the Eastern Dedicated Freight Corridor in Punjab, Union minister of state for railways Ravneet Singh Bittu on Wednesday said Railways will intensify 24-hour patrolling and significantly expand surveillance coverage along the tracks. Bittu, who visited Monday's blast site between Shambhu and Rajpura on Wednesday and reviewed the situation, said, "Special attention will be given to secluded and vulnerable sections of the corridor. Advanced monitoring methods, including drone surveillance, will be deployed. In addition, key railway personnel will conduct continuous ground patrols to ensure track safety," he said. At present, 173 CCTV cameras have been installed in the Punjab region of the Ambala division, with more installations underway. The minister highlighted that this was the second such incident within three months and within a distance of approximately 35 kilometres. The earlier incident occurred on January 23, around 800-900 metres from NH-44, while the latest blast site is located about 300 metres from the same highway. "Preliminary assessments suggest that miscreants may be exploiting easy access routes from the highway to target railway tracks," he said. These acts, he noted, were not only security threats but also attempts to disrupt economic activity in the state. The Eastern Dedicated Freight Corridor, which connects Sahnewal with West Bengal, is a vital economic artery, with approximately 30 trains operating daily to transport industrial and agricultural goods. Any disruption to this network poses a setback to both the state and national economy....
