On the side lower berths on which passengers have been booked under Reservation Against Cancellation (RAC), during the day time, sitting accommodation is also provided for those booked on the upper berth.
A person booked on side upper berth will not have any claim of seat on the lower berth between 2200 hours and 0600 hours.
