A group of school children in India are taught in their makeshift classroom – under a railway bridge. The noisy underpass doubles as a classroom for two hours each day after heroic shopkeeper Rajesh Kumar Sharma, 42, built it himself. The rudimentary learning space is situated under a Metro train bridge in a slum area of New Delhi called Yamuna Bank. It consists of two blackboards painted on a wall, two broken chairs for the teachers and simply rugs for the students to sit on. Rajesh – who set up the school after worrying about children from nearby slums missing out on an education – now has around 40 kids attending daily aged between four and 12.
