If my 1 train is late by 2 hrs and I miss my 2nd train . Can I board other train on that route with same ticket which is of train which I missed.
You are not eligible to travel in train for which you have not bought ticket. Train X ticket is invalid in Train Y. Only Sub urban Train have that kind of facility.
you are not allowed to board in reservation coach with the ticket you have missed. you can do one thing that you should file TDR with reason of train being late. you will be given your refund. meanwhile purchase one unreserved ticket or book ticket if current booking is available and then you can board the train in which you want to go.
