The service will eventually be rolled out at 400 stations across India.
Recently Mumbai Central Station became the first station to have high speed Internet facility for thousands of its passengers who travel everyday by trains.
After Mumbai Central, four stations - Jaipur, Allahabad, Ranchi and Patna - will be connected with the high-speed Wi-FI network, said a senior Railway Ministry official.
Railtel, railway's telecom arm, will provide Internet services as RailWire via its extensive fiber network at stations.
Designed to offer rail users the best Internet experience, Railwire Wi-Fi will be available to any user who has a working connection on a smartphone.
Users will be able to easily stream a high definition video while they are waiting, research their destination, or save some videos for offline viewing, download a book or a new game for the journey.
According to the railways' vision to provide world class high speed public Wi-Fi network at stations, millions of passengers at 100 stations will be able to avail the facility by the end of this year.
