Whether you should manually cancel a Waitlisted (WL) e-ticket after chart preparation on Indian Railways depends on whether the entire PNR is waitlisted. If every passenger on your e-ticket remains on the waiting list after the final chart is prepared, you should not cancel the ticket manually. The system will automatically cancel the ticket and initiate a full refund (minus a small clerkage fee) to your original payment method. However, if your ticket is "Partially Confirmed" (some passengers are confirmed/RAC and others are WL), the waitlisted passengers' names will still appear on the chart. In this case, if the WL passengers decide not to travel, you must file a Ticket Deposit Receipt (TDR) online through the IRCTC website or app at least four hours before the train's scheduled departure to claim a refund. Manually cancelling a fully waitlisted e-ticket before the system does can sometimes lead to unnecessary cancellation charges, so it is best to let the automated 2026 charting process handle the "dropped" waitlist entries for you.
