You can get train to kolkata and New Delhi from this station, basically the station serves as junction between train going to Kolkata and New Delhi
I think its a police control room
Not to my surprise, child labour is widespread in almost all Indian train stations. These are kids who collect rubbish across the train station in Allahabad and sell that to local mafia. Unfortunately in northen india exploitation of little children for labour is an accepted practice and perceived by the local population as a necessity to alleviate poverty. Children like these worked on very low wages for long hours in unhygienic conditions. Also these children support their families through their work. Parents sacrifice their children’s education to the growing needs of their younger siblings in family and view them as wage earners for the entire clan.
