I am visiting some relatives in Jammu for a week or two, and what I would like to know is if we decide to go to Vaishno Devi from there, can we easily get a train from Jammu to Katra? Some detailed which I need to know is: 1. Can I easily get a confirmed seat for the Jammu to Katra train? 2. How much is the ticket cost? 3. How long does it take from Jammu to Katra?
