Between Park Circus & Sir Gurudas Banerjee Halt one can notice this unfinished platform - the proposed site for a railway station which is supposed to come up for the adjacent Tangra area. Tangra is a region in east Kolkata that traditionally housed a large number of tanneries owned by people of Hakka Chinese origin. "47 South Tangra Road", may be the most confusing postal address, as it used to cover the whole of Chinatown Tangra with over 350 tanneries. Most of the standing structures have been built by the industrious Hakka Chinese people, upon marshy and reclaimed low-lying land. Over the past several decades, the area has served as the location of Calcutta's Chinatown. Food from Tangra is a distinct variety of traditional Hakka Chinese cuisine adapted to Indian ingredients and the Bengali palate. This has spread to the rest of India, along with the recipes earlier unique to Tangra. Tangra is now the most popular destination for Chinese food in town.
