As mentioned above, generally, the train chart preparation time is precisely 4 hours before the train departure. The final chart contains your information like name, age, gender, allotted berth, coach, and more. Trains scheduled to run their final chart at midnight are prepared at 8 PM of the previous evening.

In the Indian Railways system as of 2026, the first reservation chart is typically prepared 10 hours before the scheduled departure of the train. For trains departing early in the morning, the chart is often prepared the previous night (around 8 PM) to give passengers ample time to check their confirmation status. After the first chart is prepared, any remaining vacant seats are made available for booking through the "Current Booking" counter or the IRCTC website. A second and final chart is then prepared exactly 30 minutes before the train's departure. This final chart accounts for any last-minute cancellations or bookings made after the first chart was released. This two-step process is designed to maximize seat occupancy and provide transparency for passengers on the waiting list or in RAC (Reservation Against Cancellation) status. Once the final chart is prepared, no further online cancellations or bookings can be made for that specific journey, and the station staff will print the physical charts to be pasted on the train carriages or provided to the Ticket Examiner (TTE) for on-board verification.
