As the description says, this is not a new Train. Upgrading the existing Express into Superfast as this is the only daily connectivity in between West Bengal and Jammu-Kashmir.
Advantages:
1) Journey time saved by 10Hrs;
2) Stoppages reduced by 56%;
3)...
more... One less rake required for the daily operation; this is the most benefit as one spare rake will be available.
So kindly rate it. DO mention reason if you flag Red.
Thanks.
