Yesterday my mother 59 years old alone boarded a train from mumbai central to delhi (Rajdhani pnr = [protected]) it was a connecting train to bareilly.
Another train from delhi to bareilly was (Rajdhani 20506 pnr =[protected]
Rajdhani was 2 hours late due to which her another connecting train to bareilly missed and she struggled on delhi station, due to delay of indian railway she had to suffer, with a lot of luggage. I want refund for the ticket which was confirmed. Here i am attaching both confirmed tickets.
