Though it is against the law, the Indian Railways is one of the biggest employers of manual scavengers. Its 14,300 trains transport twenty-five million passengers across 65,000 kilometres every day. Their shit is funnelled straight onto the railway tracks through 172,000 open-discharge toilets. This shit, which must amount to several tonnes a day, is cleaned by hand, without gloves or any protective equipment, exclusively by Dalits.
