FIRSTLY...
12629 is highly preferable train for e2e pax who reside in outer regions of banglore like tumkur, ramnagar, hosur etc.
Reason- 12649 arr at 20:00 whereas 12629 arr at 06:20 so catching bus to their respective places & then reaching home in middle of night is quiet unsafe.
Well acc to my point of view 12649/50 must become daily + their should be...
more... change in dep time from NZM which could be around 22:00 which makes it arr at YPR around 09:00
*idle rake standing at NZM yard about 20hrs wiz too much.
SECONDLY...
12629/30 provides connectivity to northern karnataka to north india, re-routing it via BRC,KOTA might be a chance that it will lose its pace.NO CHANGE!!!
THIRDLY & Most Importantly...
Its a legitimate demand from GR/UBL/BAY/BGK to NDLS.
So, for such a new trains should be implemented as...
UBL,GR---NZM weekly SF LINK EXP (as GR is a new div HQ)
. via- GDG-BGK-SUR(UBL part), GR-HG(GR part) linking done at HG, SUR-PUNE-ST-BRC-KOTA.
***UBL portion ease some load of GOA Exp whereas GR portion a long pending demand.
###after seeing the performance their should always be gate remain open for their frequency increase.
