First of all, Both Duronto do have different terminal & DEE train has to negotiate via NDLS ENTRY/EXIT before making it to NZM!!
I dont think, DEE-YPR can make DEE-NZM in 11 Minutes, as been projected with uniform AVG Speed!!
DEE-NDLS: 30-35 Mins, NDLS NZM: 25-35 Mins
The total run, after nullifying NDLS congestion, comes as 55-70 Mins!!
Kindly...
more... deduct it from total 5 Hrs 30 Mins run of DEE-YPR Duronto n u gonna find it @ 4 Hrs 20-35 Mins!!
Further, i dont think it would be trailing Tamilnadu Exp till JHS/ET, as per AVG Speed Projection!!!!
