Can anyone explain me this? I had to board train today morning 8.35 PM, and unfortunately i missed it. So i was filing TDR against that PNR. But while submitting i'm getting highlighted warning. I chose reason for tdr "Passenger Not Traveled". according to my understanding we can also fill tdr after departure of the train till next 2 hrs, but not sure what it is. Can anyone explain this? or faced the similar problem.
