Hey can you people please clear my doubt about Tatkal Tickets Cancellation Maximum Duration? What I need to know is like for waiting Tatkal tickets it gets canceled automatically and amount get refunded in respective accounts. But what about RAC tickets? How to cancel a RAC Tatkal ticket? Is there any time limit to cancel Tatkal RAC tickets? And can we cancel it online or do we need to go Railway station to cancel it? So please just provide me the Tatkal Cancellation rules. Thanks.
