In the Indian Railways (IRCTC) reservation system, RLWL stands for Remote Location Waiting List. This status is assigned to tickets booked for travel between two intermediate stations on a train's route, rather than from the starting station to the final destination. The number 21 indicates your current position on that specific waitlist. When a person who has a confirmed ticket for that same "remote" segment cancels their booking, the person at RLWL 1 moves to confirmed status, and everyone else moves up. RLWL is generally considered to have a lower probability of confirmation compared to the General Waiting List (GNWL), because the quota of seats allocated for intermediate stations is much smaller. If your ticket remains in RLWL status when the final chart is prepared (usually 4 hours before departure), and it was booked online, it will be automatically cancelled and refunded. If it was purchased at a physical counter, you can still board the train but will not be guaranteed a seat or berth unless a TTE (Ticket Examiner) can find an unoccupied space during the journey.
