Yes, a Reservation Against Cancellation (RAC) ticket on Indian Railways can—and frequently does—get confirmed. When a passenger with a "Confirmed" (CNF) ticket cancels their booking, the first person on the RAC list is automatically moved into that confirmed berth. This process continues right up until the Final Chart Preparation, which usually happens 4 hours before the train's departure. Even if your ticket remains "RAC" after the chart is prepared, you are still legally allowed to board the train; the only difference is that you are guaranteed a sitting seat (usually sharing a side-lower berth with another RAC passenger) rather than a full sleeping berth. In 2026, with the introduction of new AI-based ticketing algorithms, RAC confirmation chances are more accurately predicted on the IRCTC app, allowing travelers to better gauge whether they will eventually get a full berth for their journey.
