I dont want to write but writing this thing...Anyday some major derailment is waiting in PNBE-DDU up line especially in ara-bxr section...Packing is very very bad...super bumpy tracks, super heavy jerks at 130kmph...i cannot even sit on my seat, it throws me, imagine what will happen when standing...Train can jump off tracks someday..Engg department should do some work..I am asking, is packing not done in this section...Ddu-pcoi always doing packing to make ride comfortable..
