CNF — fully confirmed

CNF (Confirmed) means you have a dedicated coach and berth number. No sharing required. Your seat is reserved for you from source to destination.

RAC — partially confirmed

RAC (Reservation Against Cancellation) means you board but share a side-lower berth. You may get a full berth if a confirmed passenger cancels or does not board — the TTE handles upgrades on the train.

Upgrade probability from RAC to CNF

RAC 1: ~95% chance of full berth. RAC 1-5: 75-95%. RAC 6-10: 60-75%. RAC 11-20: 45-60%. RAC 21-30: 15-30%. RAC 31+: under 15%.

Practical difference

With CNF, there is nothing to do — just board and find your berth. With RAC, set a WhatsApp alert to know when you get upgraded to CNF. Even if not upgraded, you will travel comfortably on a shared berth.

Frequently asked questions

Is RAC as good as CNF?

Not exactly — CNF gives you a full berth to yourself while RAC gives a shared berth. But RAC does guarantee boarding, which is much better than WL.

Can RAC become CNF before departure?

Yes — RAC can upgrade to CNF if confirmed passengers cancel before chart preparation (4-6 hours before departure). Low RAC numbers (1-5) almost always get a full berth.

What berth do I get with RAC?

RAC passengers get a side-lower berth shared with one other RAC passenger. In Sleeper and all AC classes, the RAC berth is always the side lower berth of a bay.
