From RAC to a confirmed berth
Reservation Against Cancellation is the good middle ground: you can board and travel today, and you may gain a full berth as others cancel. Here's how to read your chances.
RAC means you can travel
Unlike a waitlisted ticket, an RAC ticket is valid for boarding in reserved coaches. You’re guaranteed to travel — the only open question is whether your shared seat becomes a full berth by the time the chart is prepared.
So if you’re RAC, the sensible default is to plan your journey and track your position, rather than cancelling in a panic.
You’re assured boarding with a seat. A full berth is the upside, not the requirement.
RAC to a full berth, step by step
You start with a shared seat
Two RAC passengers are allotted one berth as seats. You're assured space on the train from the moment you're RAC.
Cancellations move you up
As confirmed passengers cancel, RAC positions convert to full berths — first at the reservation chart, sometimes again closer to departure.
Lower numbers convert first
A low RAC position has the best chance of becoming a full berth. Higher positions may travel the whole journey as a shared seat.
Reading your RAC prediction
A prediction for an RAC ticket estimates the chance of a full berth, based on how this train’s RAC has historically cleared around your booking window. A strong signal is encouraging — but even a weak one doesn’t stop you travelling.
