Good dream.
Revised and practical timings, if any train in this route is gonna come up:
SC: 09:00
VSKP: 20:00
BBS: 02:30
KGP:...
more... 06:30
HWH: 08:00
This would make a bit of possibility, because the traffic in this route is too much and this easily cannot become the KING of this route, with the likes of Coromandel, Falaknuma, BBS DRNT, BBS RAJ being the ones which will rule.
The fastest train between SC-HWH is 25 hours, this will take around 23 hours, which is possible.
