Kolkata Metro Despite the difficulties faced, services began on 24 October 1984, with the commissioning of a partial commercial service covering a distance of 3.40 km[6] with five stations served in between Esplanade and Bhowanipur (currently Netaji Bhavan). The first metro was driven by Tapan Kumar Nath and Sanjoy Sil. The service was quickly followed by commuter services on another 2.15 km stretch in the north between Dum Dum and Belgachhia on 12 November 1984. The commuter service was extended up to Tollygunge on 29 April 1986 covering a further distance of 4.24 km making the service available over a distance of 9.79 km and covering 11 stations. However, the services on the north section were suspended with effect from 26 October 1992, as this isolated small section was little used.
