IMO DHN deserves a daily SF for Delhi..If it's not happening due to either ECR or RB,they are clearly at fault here..But AFAIK ECR had proposed trains for DHN in the past but all of them had been rejected by RB..Plz put some pressure on your representatives..Only that is going to work.. Let's not engage PNBE in all these stuff..A state capital deserves at least one dedicated SF class train to Delhi.
