Indian Railways — me and my wife missed the flight due to train delay...

Dear sir,
I booked my ticket in train no. 14311 (Ala hazrat expresd) for 31mar18 from bareilly to delhi, the scheduled time of reaching delhi was 11:30am but it reached at 02:40pm more than 03hours delay.
Me and my wife had an flight from delhi to goa on at 02:25pm but due to train delay which was more than 3 hours, i had to reschedule my flight. So i had to pay 11000 more rupee.
Me and my wife had travelling insurance in train and in flight.
Kindly tell me that how can i get my compensation on this irresponsible act of indian railway.
Thanks..
