Please don't get confused with the presence of those stations which don't lie in the path of this train..Those stations indicate that some passengers had undergone Break Journey/Blank Paper Ticket/Telescopic Ticket.
For example, 1 passenger was booked for ARA-HUP..Most probably he/she would have boarded 22465 upto PRYJ and then 22684 from PRYJ to HUP..It will get counted in 22465 only..Similar for other alien pair of stations.
