India's Kolkata Metro achieved a historical feat as it became country's first to run under a river. A Metro rake ran below river Hooghly (a major tributary of river Ganga in eastern India) between Howrah Maidan and Esplanade metro stations, officials informed on Wednesday.
Up until 1912, Kolkata (then Calcutta) was the capital of India, after which the British imperial rulers moved it to New Delhi, about 1500 km to its west.
