Apparently this train has huge traction in current bookings among last-minute travelers. Traveled in it yesterday, boarding Sep 22. 21st morning there were 91 seats available. When I asked at the current booking counter for a relative, I got the reply that it is sold out! Checked in indianrail.gov.in and got Current Booking Availability as 0! Guy at the counter told me most of the times it gets full at the last minute.
