Punjab Mail is important, but those other trains are given more priority on line as observed. Many times Punjab Mail arrives late at BSL when AMI SF is there on line nearby. Punjab Mail is overtaken. I had seen parallel ghat run of Punjab Mail and AMI SF, there also AMI SF departs early ahead from kasara or sometimes made to stand at IGP while AMI SF exceeds towards ghat first. Punjab Mail is legendary king but this is the thing as OBSERVED. No personal views.
