RailTel's network passes through around 5,000 stations across the country, covering all central business districts, towns, cities, mini/major-metros.[1]

RailTel has created state of the art multimedia telecom network using SDH/DWDM-based transmission systems and high end routers for MPLS-IP network. Indian Railways have seamless right-of-way along 63,000 km of rail tracks passing through 7000 stations across the country. The stations in major cities are located in central business districts. Indian Railways already had established a strong Telecom Network to meet its communication requirements. With the formation of Corporation, Indian Railways' right-of-way and OFC assets have been transferred to RailTel. About 32500 km of OFC has been laid and over 29500 km has been commissioned. Works on another 10620 km are in various stage of completion.

RailTel holds the following licenses using which it is offering various services across India:

National Long Distance

Class "A" ISP (with Internet Telephony) IP-II IP-I

Backbone

The network supports services like layer 3 and layer 2 VPN services, broadband internet access, multicast services etc. The MPLS network has POPs at 40 cities across the country and is in the process of being extended to other important cities/towns also. The IP services at more than 3000 POPs in the country will be extended through Ethernet interface available in the SDH networks at these locations which will intern be connected to MPLS-IP backbone network at the 40 cities. The MPLS backbone supports multiple STM-1 capacity. The network is also being upgraded to Giga capacity overlaid on new DWDM network, so as to provide gigabit VPN ports for IP based voice, video and data applications.
