It cant easily get extended to BSB with hardly 7 Hrs of TAT (10 Hrs needed at least)!! And kindly dont judge train's occupancy in Pandemic Era & if its same story irrespective of Era then its route got no taker!!
Ample train exist for DDU/BSB-KYQ which is 20/24-26 Hrs (19/20 by Raj). 28-29 Hrs by this train will get no taker from BSB!!
Daily Doon Exp DEP Gaya @ 5 AM for BSB!! Its return from BSB will happen at 12:00 pm which isnt an ICE timing!!
