rac means reservation against cancellation
===================================================
When all the available seats/berths in an individual train/class have been sold, the railways start selling RAC tickets (2A, 3A, FC & SL only), when all the RAC tickets have been sold, then a waitlist is started for all the train classes, and you’re sold a waitlisted ticket.
As...
more... people cancel tickets, a RAC/WL ticket will move closer to a confirmed berth. Also, when the final reservation chart is prepared, any un-sold quota berths will be used to reduce the RAC/waitlist.
Tickets will be sold in the following order...
1.Available 02
2.Available 01
3.RAC 01
4.RAC 02
5.RAC 03
6.RAC 04
