42.Indian Railways has a launched M-Ticket

"The Indian Railways has a launched M-Ticket as a mobile phone application allowing users with an internet enabled mobile to book railway ticket through their phones. Users will need to carry the SMS that would be sent as the proof of the booking within 20 minutes of booking. Users will still need to carry a valid id proof along with the SMS for their booking to be valid.

Users will need to download the mobile ticketing application from Indian Railways’ portal IndianRailways. Users can use their mobile phones and visit the website to register for the service. An SMS will then bring the link of the mobile ticket application on the phone. Once it is installed, one can get tickets on the phone. On completion of booking and payment formalities, an SMS containing ticket details will be sent to the user, which is referred to as the Mobile Reservation Message (MRM)."
