I have been using this app from past 2 months its very helpfull and efficient. Your can book your train ticket just by sitting at home no need to stand in queue. Your can order your train meals using this app. Select the seat with your preference. You can pay online or pay on travelling. This app is only for express train. Don not have to charge extra for this they just take the internet fee which is quite low. You get your e-ticket using mail and sms. Now no need for agents to book your train ticket just download the app and sign in
