It is better to use that rake for Jammu Tawi to Shri Jaghanath Puri via Amritsar ,Chandigarh Panipat kurukshetra safdarjung bilaspur kharagpur tatanagar.
Because their is no direct train to Puri and it was a huge demand from last so many years.
It will a profitable route and help passengers and pilgrims to reach destination without changing train in Delhi or bhubneshwar.
Also...
more... one train will connect more than 6 tourist places.
Like Mata vashino devi,golden temple,Chandigarh,puri etc.
Request to indian railway minister.
