WHAT IS RAC (RESERVATION AGAINST CANCELLATION

RAC stand for Reservation Against Cancellation (RAC), and it means that you don't have a reserved berth, but you have sitting accommodation in the train and class of your choice. There is a possibility this will be converted to a berth when it becomes available due to last minute cancellations closer to travel date. RAC tickets holders can board the train and are seated in the two side chairs. If a berth is available due to cancellation, then one RAC holder will get the berth, and the other can convert the two side chair into a berth/ 

A Reservation Against Cancellation (RAC) is a type of ticket that can be purchased for travel on the Indian Railways. Although it ensures certainty of travel, it does not guarantee a berth. A berth will be allocated to the person who reserves an RAC ticket if passengers already have confirmed ticket do not turn up before the train departure or get their confirmed ticket cancelled.

A berth is split into 2 seats for 2 RAC ticket holders. If there’s any last minute cancellations, or if any quota allocations remain unsold, or if any confirmed ticket holders are given a free upgrade (more later), an RAC ticket holder is given the empty berth, the other RAC ticket holder can then convert the 2 seats into a berth
