Yes that's always what happens in every journey. The train gets good weightage from BQA, VSU-KGP. Train is meant for all the stations from PRR to KGP. After BQA, no seats are left vacant. Train is not jam-packed from PRR itself. It provides upto 60-70% occupancy and train gets 100% by the time it reaches BQA. All unreserved passengers thereafter have to stand if they get space.
