I suggest you please check the stop time of trains to other station how cn pssngrs bord n debord from train, I already written in above post stop time can be more if Loco change fro Diesel to Electric at any station. Plz find example -
Sapt Kranti - 10 mnts,10 Mnts ,15 Mnts at MB , LKO & GKP Respectively.
Gorakhdham - 10 Mnts ,15 Mnts at LKO & NDLS Respectively.
Amarnath...
more... SF Express - 15 mnts,10 Mnts ,10 Mnts , 10 Mnts , 10 Mnts at GD , LKO, MB, SRE, LDH Respectively.
Above train not change the loco in Entire Route. I would like to tell you Gorakhdham stop time at CNB is only 5 Mnts can you explain how cn pssngrs bord n debord train while everybody knows how train jam packed from GKP.
It is only few Example, If you observe the long route train, IR definitely speed up the train with cut down the stop time at major station, it can be done with Zero investment.
