Today read an interesting article in economic times on indian raliways initative to wifi enable luxury trains like rajdhani and shatabdi express. If this happens then it will surely position railways back to the business traveller segment going to tier-II towns as taking an overnite train ride does not mean remaining disconnected from work. Beside travelling economy class in cramped up seat is surely not my style but remaining disconnected for long always discourage rail travel for me.
For me if railway put the Wifi instrastructure then should look at monetizing it further by just not concentrating on providing internet access but look at VOIP and to provide calling service from the train. As telecom penentration in rural areas is still not there which means railways can help increase rural telephony penetration but if it sound much then atleast deliver free interent connection to travellers.
