Kindly understand one thing.
1) Only 2 berths are earmarked per sleeping coach (Except First AC and First Class). Not a berth more; not a berth less.
2) #lowerberthquota only applies when you book a single ticket in #generalquota. This facility applies to male above 60 years of age and female above 45 years of age (Traveling alone)
3) When a confirmed...
more... berth originally booked against
#lowerberthquota is cancelled, the same is not released to the system and is kept withheld. The same berth is released during
#chartpreparation.
4) PNR's having multiple passengers aren't considered here.
5) The same applies only for General Booking and not Tatkal Booking.
##
CRS can however manipulate the final berth allocation post the system prepares it. It may depend upon the inside sources one use to avail a
#lowerberth for his/her own.
