RailTel Corporation is planning to build a captive mobile network, spanning 63,000 km of railway tracks, for 200,000 of its employees through a closed user group. It is also planning to offer cellular coverage along railway tracks so that travelling passengers can have access to seamless connectivity. Currently BSNL, Hutchison Essar, Reliance Telecom, Idea Cellular and Tata Teleservices are negotiating with RailTel to set up a pan-Indian network with built-in special features for the railways.
