The point here is jaipur didn't demand this train. Churu sikar mp's are demanding. And i don't think anybody from jaipur will go to CDG by that route covered in 10 hrs.
That churu mp badly wants train paradise there so demanding illogical things.
They will eventually get a vandebharat, probably BKN DEC vb later. Then why are they ruining this JP CDG vb? NR bhi agree nhi krega iske upar and eventually will drop this proposal due to silly politics in Raj.
