i travel from pune to kanpur central using railway warrant AC 3 Tier ticket. can i travel to kanpur central by going first mumbai, then new delhi by rajdhani and from there to kanpur by another train using rail warrant issued by ministry of defence. i have to take this route because there is only one direct train to kanpur in a week and most of the times it gets full within first few minutes of reservation opening 90 days before departure date.
