Some more tips as I know-
1. You can book tickets even if you are at the station by scanning UTS QR code. You can find QR near ticket window or some railway station have on plateform as well.
2. If you are nearby any railway station and unable to book the ticket then please use "book and print" and you can print the ticket on AVTM.

Also you get 3% concession on using UTS wallet, if you will add 100 Rs. To your wallet thet you will get 103 Rs. Earlier it was 5% but now reduced. Hope in next days it will be 0% and after that you will pay 5% for adding money in wallet. So go and hurry up.
4. You can also book the ticket by AVTM without smart card by using UPI QR payment mode.

THANKS!
