Explanation
Before the COVID-19 pandemic, the Indian Railways transported over 23 million passengers daily, making it the largest, fastest, and most dependable mode of transportation for the transportation of trafficked women and children by suspected criminals.
Through Operation AAHT, the Indian Railways' infrastructure and intelligence network could be used to gather, organize, and analyze information about victims, trafficking routes, popular trains used by traffickers, the identity of agents and kingpins, and other crucial clues, which could be shared with other law enforcement agencies. The Railway Protection Force (RPF) could function as a connecting link between states, providing assistance to local police in their efforts to combat trafficking.
Furthermore, cyber cells will monitor the web and social media to identify digital footprints of human trafficking, with particular emphasis on trains originating from districts along the borders of Nepal, Bangladesh, and Myanmar.
