That's also true. I have two observations with this train.
1. My travelling exp from MAS-RJY. That day 50% people got down at MAS and most of AC coaches occupied at MAS only. When i asked TTE for seat to RJY , he asked me u want in 3A or 2A as many vacant seats even after MAS. Actually its a saturday night when Godavari Puskaras going on. All trains to BZA,RJY,VSKP packed at that weekend due to Puskaras but this train still has many empty tickets at MAS.
2. Yesterday...
more... night i have current booking status of this train at MAS. It say NE for all classes. That means seats not available ?? Actually DHanbad to MAS its in GNWL so people can book many tickets to MAS.
Any ways as you told only IR have data but unfortunately they wont maintain.
