If you can exploit this rule then may be you have a fringe chance:
"Further, under special circumstances like bandhs or agitations or floods, etc. where the passengers could not reach the reservation counters or stations for cancellation of tickets, a TDR (Ticket Deposit Receipt) shall be issued to the passenger upto three days after the scheduled departure of the train and the passengers may apply for refund of fare within ten days from the scheduled commencement of journey to the Chief Commercial Manager (Refunds), of the Zonal Railway concerned. The refund application shall then be considered on its merits based on the circumstances of the case."
