What is RAC in Train Tickets?
RAC stands for Reservation Against Cancellation. When you book an IRCTC train ticket and your PNR shows RAC status, it means you have a confirmed seat to travel — but you will share a berth with one other passenger instead of getting a full berth to yourself.
Specifically, a RAC berth is a side lower berth (SL) that is shared between two RAC passengers. Each gets half the berth to sit, and one may get to lie down if the other is a short-distance traveller.
RAC to Full Berth Confirmation Chances — All Numbers
The number after RAC is your position in the upgrade queue. All RAC passengers can travel; the question is whether you get a full berth. Here is a full breakdown:
| RAC number | Can travel? | Full berth chance | Advice |
|---|---|---|---|
| RAC 1–5 | Yes | 85–95% | Very likely upgrade. Set WhatsApp alert and track chart. |
| RAC 6–10 | Yes | 60–75% | Good chance. Monitor PNR in last 48 hours before departure. |
| RAC 11–20 | Yes | 30–60% | Moderate. Travel is guaranteed; full berth depends on cancellations. |
| RAC 21–30 | Yes | 15–30% | Lower chance. Expect shared berth; ask TTE on board. |
| RAC 31–50 | Yes | 8–15% | Unlikely upgrade. Keep ticket — boarding is still valid. |
| RAC 51–75 | Yes | 3–8% | Very unlikely upgrade. Travel on shared berth. |
| RAC 75+ | Yes | 1–5% | Rare upgrade. Still board and travel; ask TTE if berths are free. |
RAC vs Waitlist — What's the Difference?
Many passengers confuse RAC with Waitlist (WL). Here is the key difference:
- RAC: You are guaranteed boarding. You will travel, but share a berth.
- Waitlist (WL): You are not guaranteed boarding. You cannot board the train unless your status moves to RAC or Confirmed before chart preparation.
If your ticket shows RAC/1, RAC/2 etc., you will definitely travel. If it shows WL/45, you cannot board unless the number drops to RAC or Confirmed.
Will My RAC Ticket Get a Full Berth?
Yes — RAC tickets frequently get upgraded to a full confirmed berth. This happens when:
- Another passenger cancels their confirmed ticket
- A waitlisted passenger does not board (TTE marks their berth vacant)
- Chart preparation happens and there are spare berths
The closer your RAC number is to RAC/1, the higher your chance of getting a full berth. RAC/1 almost always gets confirmed before or during the journey.
How to Check RAC Ticket Confirmation Status
You can check your RAC PNR status on PNR Alert by entering your 10-digit PNR number. The status updates in real time as cancellations happen.
The best way to track RAC confirmation is to set up a WhatsApp alert — you will get a message the moment your RAC ticket upgrades to a confirmed berth, so you do not have to keep checking manually.
When Does RAC Chart Get Prepared?
Chart preparation typically happens 4 hours before the train's scheduled departure. At this point, all cancellations are processed and final berth allocations are made. Many RAC passengers get confirmed at this stage.
Even after chart preparation, the TTE (Train Ticket Examiner) can allot a vacant berth to you if a confirmed passenger does not board.
How Many RAC Tickets Get Confirmed?
On most long-distance trains, roughly 60–70% of RAC 1–10 passengers get a full berth either at chart preparation or during the journey. For high RAC numbers (50+), the rate drops below 10%. Class and route both matter — Sleeper class has more berths and more cancellations than 3AC.
| RAC range | Full berth upgrade chance | When does it happen? |
|---|---|---|
| RAC 1–5 | 85–95% | Usually at chart preparation |
| RAC 6–15 | 60–75% | Chart or during journey by TTE |
| RAC 16–30 | 30–50% | Mostly on-board by TTE |
| RAC 30+ | 5–15% | Only if many no-shows on train |
Will RAC 75 Get Confirmed?
RAC 75 is a high RAC number. The full berth upgrade chance is approximately 3–8% — meaning most RAC 75 passengers will travel on a shared side lower berth throughout the journey. However, boarding is guaranteed regardless of the number. If you are at RAC 75, keep the ticket and board the train. Ask the TTE at the start of your journey — on less-full trains or when many passengers alight at your starting station, upgrades do happen even at high numbers.
RAC or WL — Which Is Better?
RAC is significantly better than Waitlist (WL). With RAC, you are guaranteed to board and travel. With WL, you cannot board at all if the status does not improve before chart preparation. Here is the key rule: any RAC number is better than any WL number for travel certainty.

RAC in Railway — Class-Wise Details
RAC applies across all reserved classes in Indian Railways, but the berth type varies:
- Sleeper class (SL): Side lower berth shared between two RAC passengers. Each gets half the berth. If the other passenger alights at an intermediate station, you may get the full berth.
- 3AC (3A): Side lower berth (SL) in the AC coach, shared between two RAC passengers.
- 2AC (2A): Side lower berth shared between two RAC passengers.
- 1AC (1A): RAC rarely occurs in 1AC due to limited berth count and lower booking volumes.
The RAC seat number on your ticket tells you exactly which berth you will share. For example, "RAC/4 S3 72" means RAC position 4, Coach S3, berth 72.
What Happens to RAC on the Train?
After chart preparation, if your RAC status has not been upgraded, here is what happens on the train:
- Board the train and find your coach and berth number as shown on the ticket.
- Share the side lower berth with the other RAC passenger.
- When the TTE comes to check tickets, they may allot you a full berth if any confirmed passenger has not boarded.
- If the train is less than full on your section, the TTE will upgrade RAC passengers to vacant berths, starting from RAC/1.
In practice, most RAC passengers in Sleeper and 3AC get a full berth during the journey — especially on long-distance trains where some passengers board or alight at intermediate stations.
