I think he has to buy a unreserved ticket and board the train.Because, after chart preparation, if the normal ticket is still W/L it automatically has no value and acts as a simple money receipt(in case of PRS Ticket) to get refund and in case of E-Ticket...the above situation doesnot arise at all...because it automatically cancels out.
So after chart preparation..a W/L ticket is simply invalid.Can somebody suggest on this?...Thank you
